Industrial 1,2-Dibromobutane Bulk Procurement Price Specs
Comparing Density 1.78 g/cm3 Logistics Costs for 250kg Drums and Freight Optimization
When procuring 1,2-Dibromobutane (CAS 533-98-2) for large-scale synthesis, logistics planning must account for the specific gravity of the material. With a documented density of 1.789 g/mL at 25 °C, this halogenated organic compound is significantly heavier than water. For procurement managers optimizing freight contracts, this high density means that weight-based freight charges often exceed volume-based charges when shipping in standard 250kg drums. Unlike lighter solvents that fill container volume before hitting weight limits, 1,2-Dibromobutane shipments reach maximum payload capacity quickly. This necessitates precise load planning to avoid overweight penalties during inland transportation. Furthermore, the high mass per unit volume impacts pallet stacking configurations. Standard warehouse racking must be verified for load-bearing capacity when storing multiple layers of filled drums. Efficient freight optimization for this material involves consolidating shipments to maximize weight allowances without exceeding safety limits for Hazard Class 6.1(b) materials. Understanding this density parameter is critical for accurate landed cost calculations, as shipping fees can constitute a significant portion of the total procurement budget for heavy organic intermediates.
Industrial 1,2-Dibromobutane Bulk Procurement Price Specs vs Laboratory Grade Benchmarks
There is a distinct economic divergence between laboratory reagent grades and industrial bulk specifications. Market data indicates that laboratory-grade 1,2-Dibromobutane, often packaged in 25g or 1000g bottles, commands a premium price per kilogram due to stringent small-batch QC and packaging costs. In contrast, industrial bulk procurement focuses on cost-efficiency for tonnage-scale usage. At NINGBO INNO PHARMCHEM CO.,LTD., we structure our pricing models around bulk volumes such as 250kg drums or IBCs to align with manufacturing scale requirements. The price differential is not merely about volume; it reflects the tolerance levels for specific impurities that may be acceptable in industrial synthesis but restricted in analytical standards. Buyers should evaluate the total cost of ownership, including the cost of additional purification steps if laboratory grade is substituted for industrial grade unnecessarily. For detailed pricing structures on our high-purity organic synthesis intermediate offerings, direct engagement with our sales team is required to account for raw material fluctuations and production schedules.
| Parameter | Industrial Bulk Grade | Laboratory Reagent Grade |
|---|---|---|
| Purity Target | >98.0% (GC) | >99.0% (GC) |
| Packaging | 250kg Drum / IBC | 25g / 1000g Bottle |
| Price Indicator | Bulk Contract Rate | Premium Per Gram |
| Typical Application | Large Scale Synthesis | R&D / Analytics |
Validating COA Parameters: 1.789 g/mL Density and GC Purity >98.0% for CAS 533-98-2
Quality assurance in bulk chemical procurement relies on rigorous validation of the Certificate of Analysis (COA). Key parameters for 1,2-Dibromobutane include a density of 1.789 g/mL and a GC purity exceeding 98.0%. However, standard COA data often omits field-relevant stability indicators. From an engineering perspective, one non-standard parameter to monitor is the color stability under ambient lighting conditions. While the specification states "Colorless to Light yellow," field experience indicates that prolonged exposure to warehouse fluorescent lighting can accelerate the shift toward a light yellow hue due to trace halogen instability. This visual change does not necessarily correlate with a drop in GC purity but can trigger unnecessary QC rejects in downstream processes sensitive to colorimetric analysis. Procurement teams should specify storage conditions in their supply agreements to mitigate this. When validating incoming shipments, always cross-reference the batch-specific COA against your internal quality standards. Please refer to the batch-specific COA for exact numerical values as they may vary slightly between production runs.
UN 2810 Compliance and Hazard Class 6.1(b) Bulk Packaging for 250kg Shipments
Transporting 1,2-Dibromobutane requires strict adherence to physical safety standards defined by UN 2810. This substance falls under Hazard Class 6.1(b), indicating it is a toxic liquid. Compliance in this context refers to the physical integrity of the packaging and proper labeling rather than environmental certifications. For 250kg shipments, drums must be tested to withstand the pressure and stacking forces encountered during international transit. The packaging group is classified as III, which dictates specific construction standards for the containment vessels. It is imperative that the drums are sealed correctly to prevent leakage, as the material poses risks via inhalation and skin contact. Procurement specifications should mandate that all containers arrive with intact hazard labels and safety data sheets. NINGBO INNO PHARMCHEM CO.,LTD. ensures that all physical packaging meets the required transport regulations for hazardous materials. Buyers must verify that their logistics partners are licensed to handle Class 6.1 substances to avoid delays at ports or customs checkpoints.
Technical Specifications Impacting Transit: Boiling Point 59-60 °C/20 mmHg and Storage Temp 2-8°C
The physical properties of 1,2-Dibromobutane directly influence storage and transit protocols. The boiling point is recorded at 59-60 °C/20 mmHg, which suggests volatility under reduced pressure but stability at standard atmospheric conditions. However, the recommended storage temperature is 2-8°C. This discrepancy requires careful thermal management during shipping, especially in regions with high ambient temperatures. Exposure to heat can increase vapor pressure within sealed drums, potentially compromising gasket integrity. Conversely, the melting point is approximately -65°C, so freezing is not a concern in most logistics corridors. The critical risk is thermal degradation during prolonged transit in unventilated containers. To maintain the integrity of the industrial 1,2-dibromobutane organic intermediate substitution equivalent performance, shipments should be insulated or temperature-controlled where feasible. Deviations from the 2-8°C storage recommendation during transit should be documented upon receipt to assess potential quality impact.
