Gabapentin 60142-96-3 — China API Manufacturer | EP USP BP R&D to Production

China Manufacturing Landscape for Gabapentin

Gabapentin (CAS 60142-96-3) is a widely prescribed anticonvulsant and analgesic medication used in the treatment of epilepsy, neuropathic pain, restless legs syndrome, and various off-label pain conditions. As one of the highest-volume pharmaceutical APIs globally with multi-thousand-ton annual demand, Gabapentin manufacturing in China has achieved remarkable scale and sophistication. Our production facility is among the leading Chinese producers, supplying pharmaceutical formulators, generic drug manufacturers, and distribution companies across more than 60 countries.

The scale of Chinese Gabapentin production reflects significant investment in chemical synthesis infrastructure, process optimization, and quality systems. Our facility has been specifically designed for high-volume amino acid derivative production, combining automated large-scale synthesis with pharmacopeial-grade quality control to deliver consistent product at globally competitive pricing.

Manufacturing Process & Facility Overview

Gabapentin production at our facility employs an optimized chemical synthesis route starting from cyclohexanone, proceeding through a Strecker-type reaction to introduce the amino acid functionality, followed by hydrolysis and purification steps. The process has been refined over multiple years of commercial production to maximize yield, minimize impurity formation, and reduce environmental impact through efficient solvent recovery and waste minimization.

Our manufacturing complex features large-scale reactor banks with individual vessel capacities up to 20,000L, continuous centrifugation and filtration systems, multi-effect evaporation for solvent recovery, fluid bed dryers with inline moisture monitoring, and dedicated milling and sieving suites for particle size specification compliance. The facility operates with fully automated DCS (Distributed Control System) process control, and annual production capacity exceeds 500 metric tons of finished Gabapentin API.

Quality Standards & Multi-Pharmacopeial Compliance

Our Gabapentin API is manufactured and released in compliance with European Pharmacopoeia (EP), United States Pharmacopeia (USP), and British Pharmacopoeia (BP) monograph specifications. The complete analytical testing program includes assay by HPLC (purity ≥99.0%), identification by IR spectroscopy and HPLC retention time, related substances analysis including Gabapentin lactam and other specified impurities, residual solvent determination per ICH Q3C, water content by Karl Fischer, heavy metals by ICP-OES, and particle size distribution analysis.

Particular attention is paid to control of the Gabapentin lactam impurity, a known process-related and degradation impurity. Our process conditions and storage protocols are optimized to minimize lactam formation, and every batch is tested against tight specification limits. The QC laboratory operates a complete instrument suite with method validation documentation meeting ICH Q2(R1) requirements for all release testing methods.

Regulatory Documentation & Export Support

Our Gabapentin API is supported by extensive regulatory filings including US FDA Drug Master File (DMF), EDQM Certificate of Suitability (CEP) for European market access, and WHO Prequalification documentation. We have successfully supported customer ANDA filings, European marketing authorization applications, and registrations across Asia, Latin America, Africa, and the Middle East. Standard documentation includes batch Certificates of Analysis, MSDS/SDS, stability data packages, and process validation summaries.

Our regulatory affairs team provides responsive support for customer regulatory activities, including timely responses to regulatory authority questions, post-approval variation submissions, and ongoing compliance monitoring. We maintain active awareness of pharmacopeial monograph revisions and proactively update specifications as required.

Packaging & Global Logistics

Gabapentin API is packaged in double-layer polyethylene bags within fiber drums, with standard net weights of 25 kg per drum. Bulk packaging options in 50 kg drums and 500 kg flexible intermediate bulk containers (FIBCs) are available for high-volume customers. All packaging is conducted under controlled humidity conditions to prevent moisture uptake, and each unit is sealed with tamper-evident closures and complete GHS-compliant labeling.

We maintain established logistics partnerships enabling efficient global distribution under FOB, CIF, and DDP terms. Full container load (FCL) shipments for large orders provide optimal cost efficiency, while LCL consolidation services accommodate smaller volumes. Standard ocean freight transit times are 18-25 days to Europe and 25-35 days to the Americas. Expedited air freight is available within 5-7 business days for urgent requirements.

Competitive Pricing & Supply Reliability

Our large-scale production infrastructure and optimized manufacturing processes position us among the most cost-competitive Gabapentin producers globally. Competitive pricing eliminates intermediary margins, and we offer complete pricing programs including volume-tiered discounts, quarterly and annual contract pricing with lock-in options, and development-to-commercial pricing transitions for new product launches.

With substantial production capacity and efficient inventory management, we maintain continuous stock availability with safety stock levels supporting immediate fulfillment of standard orders. Our supply chain resilience is demonstrated by an unbroken supply record and on-time delivery performance exceeding 98% across all customer accounts globally.
