Neostigmine bromide
Neostigmine bromide from Hangzhou Sida Organic Chemical Co., Ltd. is a USP 29 grade pharmaceutical compound with a molecular formula of C12H19BrN2O2, supplied as a white or almost white crystalline powder. The assay range is strictly controlled between 98.0% and 101.0%, ensuring compliance with international pharmacopoeia standards. It is classified under HS code 2923.90 for cross-border trade and is packaged in pharmaceutical-grade HDPE drums or fiber drums for bulk export.
As a quaternary ammonium salt, neostigmine bromide acts as a cholinesterase inhibitor, making it a critical active pharmaceutical ingredient (API) for reversing neuromuscular blockade in anesthesia and treating myasthenia gravis. The product is typically synthesized under GMP conditions, with residual solvents and heavy metals monitored to meet USP 29 limits. Standard purity tests include HPLC for assay determination and thin-layer chromatography for identity confirmation.
This compound is primarily sourced by pharmaceutical manufacturers, research institutions, and hospitals requiring precise dosing for clinical applications. Importers should confirm packaging options, which commonly include 1kg bags or 25kg drums, and verify compliance with destination market regulations. Bulk shipments are typically quoted per kilogram or metric ton, with trade terms and incoterms negotiated based on order volume.

Sourcing Neostigmine bromide from Hangzhou Sida Organic Chemical Co., Ltd. - China Import Guide
Before ordering neostigmine bromide, verify the supplier’s ability to provide a certificate of analysis (CoA) that confirms the assay range of 98.0-101.0% and compliance with USP 29 standards. Check that the CoA includes results for identity, purity, residual solvents, and heavy metals, as these are critical for pharmaceutical applications. Request samples for independent testing if your procurement policy requires third-party validation.
Confirm logistics details such as packaging type (1kg bags or 25kg drums), dimensional weight, and compatibility with your storage facilities. Clarify the incoterms (e.g., FOB Hangzhou) and payment terms, as these impact landed costs and risk allocation. For air or sea freight, ensure the packaging meets IATA or IMDG regulations for hazardous or non-hazardous chemical shipments.
Quality checks should include visual inspection for color and crystalline structure, as well as laboratory tests for assay and impurities upon receipt. Request the supplier’s recommended test methods and acceptance criteria to align with your quality control protocols. Documentation such as the MSDS, CoA, and origin certificates (e.g., China Customs Declaration) must accompany the shipment to facilitate customs clearance and regulatory compliance.
