Factory Direct 4-(2-Aminoethyl)Benzenesulfonamide Bulk Price & Supply Chain Analysis
- Process Chemistry: Optimized reduction pathways ensure consistent yields above 85% with minimal nitro-impurities.
- Sourcing Logistics: Direct manufacturing eliminates distributor markups, securing competitive tonnage rates.
- Commercial Viability: Full regulatory documentation supports seamless integration into GMP production lines.
In the pharmaceutical intermediate sector, securing a reliable supply chain for key building blocks is paramount for maintaining production schedules and margin integrity. 4-(2-Aminoethyl)benzenesulfonamide (CAS: 35303-76-5) serves as a critical Glipizide intermediate used in the manufacture of second-generation sulfonylurea antidiabetic agents. For process chemists and procurement officers, understanding the disparity between laboratory-scale costs and factory direct industrial pricing is essential for accurate budget forecasting. As a premier global manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. specializes in delivering this compound with the consistency required for large-scale API synthesis.
Technical Specifications and Synthesis Overview
For R&D teams evaluating this molecule for process scale-up, the synthesis route significantly impacts the impurity profile and downstream purification costs. The most commercially viable production method involves the reduction of 4-(2-nitroethyl)benzenesulfonamide or the chlorosulfonation of phenethylamine followed by amination. Achieving industrial purity requires strict control over the reduction step to prevent the formation of hydroxylamine intermediates or azo-coupling byproducts.
High-performance liquid chromatography (HPLC) analysis is standard for verifying assay purity. Batch-to-batch consistency is maintained through rigorous crystallization protocols, ensuring the material meets the stringent requirements for pharmaceutical applications. The following table outlines the critical quality attributes expected from a top-tier supplier:
| Parameter | Specification | Test Method |
|---|---|---|
| CAS Number | 35303-76-5 | N/A |
| Molecular Formula | C8H12N2O2S | N/A |
| Molecular Weight | 200.26 g/mol | Calculated |
| Assay (Purity) | ≥ 98.0% | HPLC |
| Melting Point | 148°C - 150°C | DSC / Capillary |
| Physical Form | Crystalline Powder | Visual |
| Heavy Metals | ≤ 10 ppm | ICP-MS |
Comparative Analysis of Lab Scale vs Factory Direct Pricing
Procurement professionals often encounter significant price volatility when sourcing fine chemicals through general laboratory suppliers versus specialized chemical manufacturers. Small-scale vendors typically package materials in 25g to 1kg units, carrying a substantial premium due to handling, repackaging, and distribution layers. In contrast, engaging directly with the source allows buyers to access true bulk price structures.
When evaluating suppliers for 4-(2-Aminoethyl)benzenesulfonamide, it is crucial to request cost breakdowns based on metric ton equivalents rather than gram prices. Laboratory grades may list prices exceeding $250 per kilogram for small quantities, whereas industrial contracts negotiated directly with the manufacturer can reduce unit costs significantly. This cost efficiency is vital for maintaining competitiveness in the generic pharmaceutical market.
Volume Discount Tiers for Industrial Bulk Orders
Scalability is a primary concern for executives planning long-term production runs. Pricing models should reflect volume commitments, with clear tiers for 25kg, 100kg, and drum-level quantities. Establishing a framework for quality assurance at these volumes ensures that the material performs consistently in reactor settings without requiring additional purification steps that erode margins.
Most reputable manufacturers offer structured discounting for annual take-or-pay agreements. This stability protects buyers from raw material fluctuations in the sulfonamide supply chain. Furthermore, securing a dedicated production line slot guarantees availability during peak demand periods, preventing costly manufacturing downtimes.
FOB Terms and Global Shipping Cost Estimates
Logistics and regulatory compliance form the backbone of a successful import strategy. Executives must verify that the supplier adheres to international safety standards, including proper classification under UN 3259 for amines. Documentation such as the Certificate of Analysis (COA), Safety Data Sheet (SDS), and Statement of Origin must be provided promptly to facilitate customs clearance.
At NINGBO INNO PHARMCHEM CO.,LTD., we prioritize transparent FOB terms and efficient packaging to minimize shipping weights and costs. Whether utilizing sea freight for large tonnage or air freight for urgent pilot batches, our logistics team ensures that all hazardous material declarations are accurate.
