DBNPA 99% Min Purity Procurement Specs & COA Guide
Essential DBNPA 99% Min Purity Procurement Specs and CAS 10222-01-2 Verification
Procurement of 2,2-Dibromo-3-nitrilopropionamide requires strict adherence to physical and chemical parameters to ensure efficacy as an industrial biocide. The CAS registry number 10222-01-2 must be verified on all documentation to prevent substitution with lower-grade brominated compounds. High-purity grades intended for cooling water treatment and paper mill applications typically present as white crystalline powder with a minimum assay of 99%. Deviations in melting point or moisture content directly impact solubility and hydrolysis rates in aqueous systems.
Technical buyers must validate the molecular formula C3H2Br2N2O and molecular weight of 241.87 g/mol against provided specifications. At NINGBO INNO PHARMCHEM CO.,LTD., quality control protocols enforce tight tolerances on these fundamental properties to ensure consistent performance across batches. The following table outlines the critical procurement specifications for commercial-grade DBNPA compared against standard theoretical values.
| Parameter | Standard Specification | Theoretical Value | Test Method |
|---|---|---|---|
| CAS Number | 10222-01-2 | 10222-01-2 | Registry Verification |
| Purity (Assay) | 99.0% Min | 100% | HPLC / GC-MS |
| Melting Point | 122-125 °C | 124 °C | DSC / Capillary |
| Moisture Content | 0.5% Max | 0% | Karl Fischer |
| Appearance | White Crystal Powder | White Solid | Visual / Colorimeter |
| Molecular Weight | 241.87 g/mol | 241.87 g/mol | Mass Spectrometry |

Auditing DBNPA Certificate of Analysis (COA) for Quality Assurance
A Certificate of Analysis (COA) serves as the primary document for verifying batch consistency and chemical integrity. Procurement teams must scrutinize the COA for specific analytical data rather than generic pass/fail statements. Key metrics include the specific retention time from Gas Chromatography-Mass Spectrometry (GC-MS) and the area percentage corresponding to the main peak. A purity claim of 99% min must be supported by chromatographic evidence showing negligible interference from adjacent peaks.
Furthermore, the COA should detail the moisture content determined by Karl Fischer titration, as excess water accelerates hydrolysis during storage. For applications in the paper industry, where pH sensitivity is critical, the COA should also report the pH of a standard solution. Understanding these data points is essential when evaluating a 2,2-Dibromo-3-nitrilopropionamide drop-in replacement for 20% DBNPA biocide paper mill strategy. Discrepancies in moisture or assay between the COA and actual received goods indicate potential degradation during transit or inadequate sealing at the manufacturing source.
Verifying Impurity Profiles and Synthesis Byproducts in Commercial DBNPA Grades
The synthesis of 2,2-Dibromo-3-nitrilopropionamide typically involves the bromination of cyanoacetamide. This reaction pathway can generate specific byproducts that affect the stability and toxicity profile of the final product. Common impurities include residual hydrogen bromide (HBr), unreacted monobromo intermediates, and dibromoacetonitrile. High levels of acidic byproducts can lower the pH of the final formulation, causing corrosion issues in metalworking fluid additive systems or cooling towers.
Advanced quality assurance requires quantifying these impurities rather than simply measuring total purity. The table below compares acceptable impurity limits against typical synthesis outputs.
| Impurity / Byproduct | Source | Acceptable Limit | Impact on Application |
|---|---|---|---|
| Hydrogen Bromide (HBr) | Reaction Byproduct | < 0.1% | Corrosivity, pH instability |
| Monobromo Intermediate | Incomplete Reaction | < 0.5% | Reduced biocidal efficacy |
| Dibromoacetonitrile | Side Reaction | < 0.2% | Toxicity profile variation |
| Heavy Metals | Catalyst Residue | < 10 ppm | Product discoloration, safety |
Controlling these variables is vital for formulators developing stable emulsions. For further technical details on maintaining chemical integrity in complex mixtures, consult the 2,2-Dibromo-3-nitrilopropionamide formulation guide for metalworking fluids stability. Low-quality grades with high impurity loads may exhibit rapid degradation, leading to loss of performance benchmark standards in industrial trials.
Navigating Hazard Symbols and Risk Codes for DBNPA Bulk Procurement
Safety compliance for bulk chemical procurement relies on accurate interpretation of hazard symbols and risk codes provided in the Safety Data Sheet (SDS). For CAS 10222-01-2, standard hazard symbols include 'C' (Corrosive) and 'Xn' (Harmful). These classifications dictate the required personal protective equipment (PPE) and storage conditions. Risk codes such as 34 (Causes burns), 43 (May cause sensitization by skin contact), and 20/21/22 (Harmful by inhalation, skin contact, and ingestion) must be clearly communicated to logistics and handling personnel.
Procurement specifications should mandate that all shipments include an up-to-date SDS reflecting these codes. The safety statement codes 26 (In case of contact with eyes, rinse immediately), 36/37/39 (Wear suitable protective clothing, gloves, and eye/face protection), and 45 (In case of accident or if you feel unwell, seek medical advice immediately) define the emergency response protocol. Verification of these safety parameters ensures alignment with internal EHS guidelines without relying on external regulatory claims. Proper classification prevents mishandling during transfer from bulk containers to process tanks.
Ensuring Stability Through Proper Storage and Logistics for 2,2-Dibromo-3-nitrilopropionamide
Chemical stability is a function of environmental control during storage and transit. 2,2-Dibromo-3-nitrilopropionamide is susceptible to hydrolysis in the presence of moisture and elevated temperatures. To maintain the 99% min purity specification, the material must be stored in tightly closed containers in a cool, dry place. Standard packaging includes 25kg cardboard drums, plastic woven bags, or 500kg jumbo bags, all of which must possess adequate moisture barriers.
Logistics providers must be instructed to avoid exposure to direct sunlight and humidity extremes. Degradation manifests as a decrease in assay purity and an increase in acidity due to bromine release. NINGBO INNO PHARMCHEM CO.,LTD. utilizes specialized packaging protocols to mitigate these risks during global shipment. For liquid formulations such as the 20% solution, stability is managed through pH buffering and temperature control in IBCs or plastic drums. Adhering to these storage guidelines preserves the efficacy of the paper mill fungicide and ensures the material meets specification upon arrival at the manufacturing site.
Strict adherence to these technical specifications and safety protocols ensures the reliable integration of DBNPA into industrial processes. To request a batch-specific COA, SDS, or secure a bulk pricing quote, please contact our technical sales team.
