For procurement managers in the pharmaceutical industry, securing high-quality raw materials is paramount. One such critical compound is 3-Chlorophenylglycine, identified by its CAS number 7292-71-9. As a vital intermediate in the synthesis of pharmaceuticals, particularly synthetic penicillins, its reliable supply chain is a constant focus. This guide aims to equip you with the knowledge to effectively buy this essential chemical.

Understanding 3-Chlorophenylglycine (CAS 7292-71-9)
3-Chlorophenylglycine, also known by its systematic name Benzeneacetic acid, alpha-amino-3-chloro-, is an amino acid derivative. Its chemical structure lends itself to crucial roles in organic synthesis. Its primary application lies in being an intermediate for synthetic penicillins, a cornerstone class of antibiotics. Furthermore, it is indispensable in drug development research, particularly in exploring structure-activity relationships (SAR) of various drug candidates, helping scientists understand how molecular structure influences biological activity.

Key Considerations When Buying
When looking to purchase 3-Chlorophenylglycine, several factors are crucial for B2B buyers:

1. Purity and Specifications: The compound is typically offered with high purity, often exceeding 95% and frequently reaching 99%. Always verify the Certificate of Analysis (CoA) to ensure it meets your specific requirements for pharmaceutical synthesis or research. Ask for detailed product specifications and batch-specific purity data.

2. Supplier Reliability: For consistent supply and quality, it is vital to partner with reputable manufacturers and suppliers. China has emerged as a global hub for chemical manufacturing, offering competitive pricing and substantial production capacities. When sourcing from China, look for suppliers with established quality control systems, international certifications (like ISO), and a proven track record.

3. Pricing and Negotiation: The price of 3-Chlorophenylglycine can vary based on purity, quantity, and supplier. As a discerning buyer, engage with multiple suppliers to compare quotes. Discuss bulk purchase discounts and long-term supply agreements to secure favourable pricing. Understanding the market price for this pharmaceutical intermediate is key to successful negotiation.

4. Logistics and Delivery: Ensure the supplier can meet your delivery timelines. Discuss Incoterms (FOB, CFR, CIF) and confirm shipping methods (ocean, air). Factors like packaging (e.g., 25kg drums) and port of shipment (e.g., Shanghai, Qingdao) are also important logistical details.

5. Payment Terms: Be clear on acceptable payment methods (L/C, T/T, D/P, PayPal, etc.) and terms. Many manufacturers in China offer flexible payment options for established clients.

Finding a Manufacturer and Supplier
When searching for a reliable manufacturer or supplier of 3-Chlorophenylglycine in China, use precise search terms such as '3-Chlorophenylglycine manufacturer China,' 'CAS 7292-71-9 supplier,' or 'buy pharmaceutical intermediate China.' Look for companies that clearly state their product specifications, production capacity, and commitment to quality. Engaging directly with manufacturers often provides the best prices and shortest lead times for bulk orders.

In conclusion, procuring 3-Chlorophenylglycine (CAS 7292-71-9) involves careful consideration of purity, supplier reliability, pricing, and logistics. By partnering with experienced China manufacturers and suppliers, you can ensure a stable and cost-effective supply of this critical pharmaceutical intermediate, paving the way for successful product development and manufacturing.
