Neostigmine methylsulfate
Neostigmine methylsulfate (C13H22N2O6S) is supplied by Hangzhou Sida Organic Chemical Co., Ltd. as a pharmaceutical-grade active pharmaceutical ingredient. The material complies with USP, BP and EP monographs and carries the CAS number 51-60-5. It is presented in bulk packaging that meets pharmacopeial standards, and the supplier states that it is sourced from GMP-compliant manufacturers. The product is intended for use in formulations requiring a reversible cholinesterase inhibitor.
The compound belongs to the heterocyclic organic class and is typically offered with a purity of at least 99% as required for clinical applications. In the pharmaceutical industry, such APIs are stored under controlled temperature and humidity to preserve stability; typical storage conditions are 15-30°C and relative humidity below 60%. Bulk shipments are usually placed in pharmaceutical-grade drums or HDPE containers that protect against moisture ingress and contamination. These handling practices align with standard good manufacturing practice for API distribution.
Neostigmine methylsulfate is used to reverse non-depolarising muscle relaxants during anaesthesia and to manage myasthenia gravis, making it a core ingredient for contract manufacturers of injectable drugs and research laboratories. Buyers generally include pharmaceutical formulation companies and academic institutions that require reliable API supplies. Trade terms are negotiated per order, with options such as FOB shipping and T/T payment, and the supplier notes flexibility in minimum order quantities to suit production scales.

Sourcing Neostigmine methylsulfate from Hangzhou Sida Organic Chemical Co., Ltd. - China Import Guide
Before placing an order, verify the supplier’s GMP compliance documentation and request the latest ISO or SGS certificates that correspond to the specific batch. Confirm that the CAS number, purity and assay results match the specifications required for your formulation, and ask for a Certificate of Analysis (CoA) before shipment.
Logistics for bulk API imports from China typically involve FOB terms from the port of Shanghai or Ningbo, with the buyer arranging sea freight. Ask the supplier to confirm the lead time for container loading, as well as the preferred Incoterms and payment schedule, which are commonly T/T against a Proforma Invoice. Ensure that the packaging meets pharmaceutical-grade standards to avoid contamination during transport.
Implement a pre-shipment inspection by an accredited third-party laboratory to validate purity, assay and moisture content against the CoA. Upon arrival, conduct a quarantine sampling and review the accompanying documentation, including the Material Safety Data Sheet (MSDS) and customs clearance paperwork. These steps help guarantee that the API meets regulatory requirements before it enters your manufacturing line.
