Framycetin Sulphate 4146-30-9 — China API Manufacturer | BP EP R&D to Production

China Manufacturing Landscape for Framycetin Sulphate

Framycetin Sulphate (CAS 4146-30-9), also known as Neomycin B Sulphate, is an aminoglycoside antibiotic widely used in topical pharmaceutical preparations for the treatment of bacterial skin infections, eye infections, and ear infections. It remains a mainstay in dermatological and ophthalmic formulations across global markets. China is a principal manufacturing hub for aminoglycoside antibiotics, and our production facility produces Framycetin Sulphate through established fermentation and purification processes, serving pharmaceutical formulators across Europe, Asia, the Middle East, and Latin America.

Chinese aminoglycoside manufacturing has matured considerably, with modern facilities incorporating advanced fermentation technology, sophisticated purification systems, and complete quality control infrastructure. Our facility combines this technical capability with competitive production economics, providing international buyers with a cost-effective and compliant sourcing solution for Framycetin Sulphate API.

Manufacturing Process & Facility Overview

Framycetin Sulphate is produced at our facility through fermentation of Streptomyces fradiae, followed by multi-stage extraction, purification, and salt formation. The fermentation process operates in stirred-tank bioreactors with volumes up to 30,000L, with automated control of dissolved oxygen, pH, temperature, and nutrient feeding profiles optimized through decades of process development. Post-fermentation processing includes filtration, ion-exchange chromatography, activated carbon treatment, concentration, and crystallization of the sulphate salt.

The production facility encompasses dedicated fermentation suites with sterile air supply systems, downstream processing areas with validated cleaning procedures, and finished product handling zones maintained under controlled environmental conditions. The integrated waste treatment system processes all fermentation residues and chemical waste streams in compliance with Chinese environmental regulations, and the facility holds all required environmental discharge permits.

Quality Standards & Multi-Pharmacopeial Compliance

Our Framycetin Sulphate API is manufactured and tested in compliance with British Pharmacopoeia (BP) and European Pharmacopoeia (EP) monograph specifications. The quality control program includes potency assay by microbiological method or HPLC (≥680 IU/mg on anhydrous basis), identification by specific color reactions and chromatographic methods, related substances analysis including neomycin C content limitation, pH determination, water content by Karl Fischer titration, sulphate content, heavy metals testing, and bacterial endotoxin analysis.

The component ratio of Neomycin B (Framycetin) is carefully controlled through optimized fermentation conditions and purification protocols to ensure the product meets pharmacopeial requirements for Framycetin content. Our QC laboratory is equipped with bioassay capabilities, validated HPLC systems, and microbiological testing suites for complete product characterization.

Regulatory Documentation & Export Support

We provide full regulatory documentation packages to support customer drug registration and import activities. Standard documentation includes batch-specific Certificates of Analysis with potency and purity data, Drug Master File (DMF) documentation, Certificates of Quality Compliance, MSDS/SDS in GHS format, TSE/BSE free declarations, and stability study data under ICH conditions. For European market access, we provide documentation aligned with EDQM requirements and can support CEP applications.

Our regulatory affairs team maintains up-to-date knowledge of international regulatory requirements for aminoglycoside antibiotics and provides technical support for customer registration activities across regulated and emerging markets worldwide.

Packaging & Global Logistics

Framycetin Sulphate is packaged in double-layer polyethylene bags within fiber drums, with standard net weights of 25 kg per drum. Smaller packaging units of 1 kg, 5 kg, and 10 kg are available for trial orders and smaller-scale production requirements. All packaging materials meet pharmaceutical-grade standards, and containers are sealed to protect against moisture ingress with complete lot traceability labeling.

International shipping is coordinated through experienced freight forwarders with pharmaceutical cold chain capabilities where required. We offer FOB, CIF, and DDP shipping terms with transit times of 18-25 days by ocean freight to European ports and 20-30 days to other major global destinations. Expedited air freight delivery is available within 5-7 business days for urgent requirements.

Competitive Pricing & Supply Reliability

Our integrated fermentation-to-finished-product manufacturing model provides significant cost advantages, enabling competitive pricing for Framycetin Sulphate that is highly competitive against global alternatives. We offer flexible pricing programs including volume discounts, annual supply contracts with price stability provisions, and preferential terms for strategic partnership accounts.

Supply reliability is supported by year-round fermentation production capability, strategic raw material inventory management, and maintained safety stock of finished API. Our track record demonstrates consistent on-time delivery performance exceeding 96%, with dedicated account management ensuring responsive communication and proactive supply chain management for each customer.
