1,2-Bis(Bromoacetoxy)Ethane 98% Purity Specs & Data

Verified 98% Purity Specifications and Physical Constants for 1,2-bis(bromoacetoxy)ethane

Technical procurement of 1,2-bis(bromoacetoxy)ethane (CAS: 3785-34-0) requires strict adherence to physical constants that dictate processing parameters. This bromoacetate ester, also recognized in industry databases as Ethylene glycol dibromoacetate, presents specific density and thermal properties essential for separation and formulation. At NINGBO INNO PHARMCHEM CO.,LTD., batch release is contingent upon verifying these constants against established benchmarks to ensure high purity performance in downstream applications.

The molecular structure, defined by the formula C6H8Br2O4 and a molecular weight of 303.93 g/mol, influences the compound's behavior in solvent systems. The density of 1.888 g/cm³ indicates a heavy organic liquid, which impacts volumetric dosing calculations in industrial reactors. Furthermore, the boiling point of 310.7ºC at 760 mmHg necessitates vacuum distillation protocols for purification to prevent thermal degradation. The following table contrasts standard literature data with commercial-grade specifications required for consistent manufacturing.

Parameter	Standard Literature Value	Commercial 98% Specification	Measurement Method
CAS Number	3785-34-0	3785-34-0	Verified
Molecular Weight	303.93 g/mol	303.93 ± 0.5 g/mol	Mass Spectrometry
Density	1.888 g/cm³	1.88 - 1.90 g/cm³ @ 25ºC	ASTM D4052
Boiling Point	310.7ºC @ 760 mmHg	178ºC @ Reduced Pressure	Distillation
Refractive Index	1.519	1.515 - 1.525	ASTM D1218
Purity (GC-MS)	Variable (63-88%)	≥ 98.0% Area Normalization	Gas Chromatography

Discrepancies in density or refractive index often signal the presence of unreacted glycol or mono-ester intermediates. Maintaining the refractive index within the 1.515 to 1.525 range is critical for ensuring the material functions correctly as a water treatment chemical or intermediate in organic synthesis. Procurement teams should request Certificates of Analysis (COA) that explicitly list these physical constants alongside chromatographic purity data.

Quality Control Protocols Differentiating 98% Grade from Standard Literature Yields

Academic literature often reports synthesis yields for 1,2-bis(bromoacetoxy)ethane ranging between 63% and 88%, depending on the catalytic system and purification method employed. However, industrial applications demand a minimum of 98% purity to prevent side reactions and ensure stoichiometric accuracy. Standard laboratory preparations may leave residual bromoacetic acid or ethylene glycol, which can interfere with subsequent reaction steps or compromise the stability of a biocide formulation.

Advanced quality control utilizes Gas Chromatography-Mass Spectrometry (GC-MS) to identify trace impurities that titration methods might miss. The separation of the di-ester from the mono-ester is particularly challenging due to similar polarities. Robust QC protocols involve checking the InChIKey (WGHAPLWNJPAJDE-UHFFFAOYSA-N) and SMILES structure (O=C(CBr)OCCOC(=O)CBr) against spectral libraries. For facilities evaluating this compound as a 1,2-Bis(bromoacetoxy)ethane superior alternative to bis(2-bromoethoxy)ethane, verifying the absence of ether linkages is paramount to ensure the desired reactivity profile is maintained.

Batch-to-batch consistency is achieved through controlled esterification conditions and rigorous fractional distillation. Suppliers capable of providing technical support will offer detailed chromatograms showing the absence of peaks corresponding to starting materials. This level of documentation distinguishes pharmaceutical-grade intermediates from technical-grade commodities, ensuring that the material performs reliably in sensitive catalytic cycles or polymerization processes.

Procurement Compliance: HS Code 2915900090, Hazard Codes, and MSDS Data

International logistics for 1,2-bis(bromoacetoxy)ethane are governed by specific Harmonized System (HS) codes that determine tariff rates and inspection requirements. The correct classification is HS Code 2915900090, which covers other saturated acyclic monocarboxylic acids and their derivatives. This classification often carries a VAT of 17.0% and a tax rebate rate of 9.0% in specific jurisdictions, impacting the landed cost calculations for bulk imports. Accurate coding prevents customs delays and ensures compliance with inward and outward inspection certificates.

Safety data is categorized under Hazard Code Xn (Harmful) and GHS07. The material carries hazard statements H227 (Combustible liquid), H302 (Harmful if swallowed), H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation). Precautionary statements P261 and P305+P351+P338 mandate the use of protective equipment and specific first aid measures in case of exposure. A comprehensive MSDS must accompany every shipment, detailing these risks and the appropriate personal protective equipment (PPE) for handling.

Regulatory compliance extends beyond safety to include documentation of origin and composition. As a global manufacturer, ensuring a stable supply involves maintaining inventory levels that meet these regulatory standards without interruption. Procurement officers should verify that the supplier's MSDS aligns with the latest GHS revisions and that the HS code matches the destination country's import regulations to avoid punitive tariffs or seizure of goods.

Storage Stability, Flash Point 141.7ºC Safety, and Bulk Packaging Requirements

The thermal stability of 1,2-bis(bromoacetoxy)ethane is characterized by a flash point of 141.7ºC. While this indicates a combustible liquid rather than a highly flammable one, it necessitates storage in cool, well-ventilated areas away from ignition sources. The material should be kept in tightly closed containers to prevent moisture ingress, which could lead to hydrolysis back into bromoacetic acid and glycol. Long-term stability is enhanced by storing the compound under nitrogen blanketing if extended shelf life is required for large stockpiles.

Bulk packaging typically involves 25kg drums or 200kg iron drums, depending on the volume ordered. For larger logistics operations, Intermediate Bulk Containers (IBCs) may be utilized, provided they are compatible with halogenated organic esters. Packaging integrity is critical to prevent leaks that could pose environmental hazards or safety risks during transport. The density of the liquid requires packaging materials capable of withstanding the specific gravity without deformation.

When formulating this compound as an industrial fungicide or corrosion inhibitor, compatibility with storage tank materials must be verified. Stainless steel or lined carbon steel is generally recommended to prevent corrosion of the storage vessel itself. Regular inspection of storage containers for signs of degradation or leakage is part of standard site safety protocols. Ensuring the flash point remains stable over time confirms that no volatile low-molecular-weight contaminants have accumulated during storage.

Sourcing Reliable 1,2-bis(bromoacetoxy)ethane 98% for Industrial Catalysis Applications

Reliable sourcing of 1,2-bis(bromoacetoxy)ethane is critical for industries relying on precise halogenation or esterification reactions. In industrial catalysis, impurity profiles can poison catalysts or alter reaction kinetics, leading to reduced yields and increased waste. Therefore, selecting a supplier who guarantees 98% purity via GC-MS analysis is non-negotiable for high-value synthesis. This compound serves as a versatile intermediate, functioning effectively as an algaecide agent in specific water treatment chemical applications where controlled release of bromine species is required.
