Import 5-Aminotetrazole — Buy in Bulk from Supplier in China

5-Aminotetrazole (CAS 4418-61-5, molecular formula CH3N5, molecular weight 85.06 g/mol) is a heterocyclic organic compound serving as a critical intermediate in pharmaceutical synthesis, agrochemical development, and energetic material formulation. Changzhou Wenshuo International Trade Co., Ltd supplies this compound from Jiangsu Province, China, an established chemical manufacturing region with deep expertise in fine chemical production. The material is typically supplied as a white to off-white crystalline powder with high purity specifications essential for downstream synthesis of active pharmaceutical ingredients and specialty chemicals.

The compound features a tetrazole ring system with an amino substituent at the 5-position, conferring both acidic and basic character that enables its use in diverse reaction chemistries. Standard material grades for industrial applications typically achieve purity levels of 98.0% minimum by HPLC, with moisture content controlled below 0.5% to prevent degradation during storage and handling. The product is sensitive to strong oxidising agents and should be stored under dry, cool conditions away from incompatible materials. Typical packaging for bulk pharmaceutical intermediate shipments includes 25 kg net weight fibre drums with polyethylene liner, though specific packaging configurations should be confirmed directly with the supplier for each order.

Primary buyers include pharmaceutical manufacturers developing antihypertensive and cardiovascular APIs, agrochemical companies synthesising crop protection agents, and research institutions exploring tetrazole chemistry for novel energetic materials. The compound's role as a building block in azide-free click chemistry variants has expanded its relevance in medicinal chemistry programmes. Trade terms referenced in the supplier's profile include FOB and CIF options, with letter of credit and telegraphic transfer payment methods available. Buyers should confirm minimum order quantities, exact purity certificates, and current lead times directly with Changzhou Wenshuo International Trade Co., Ltd, as these operational details are not fixed in the listing data.

Changzhou Wenshuo International Trade Co., Ltd is registered at Guanhe Road, Changzhou 213003, Jiangsu Province, China, positioning the company within one of China's most concentrated fine chemical manufacturing corridors. The supplier holds an imported tier classification and harbour trust tier, indicating engagement with international trade though not the highest verification level available on the platform. Notably, the response rate is recorded at 0.00% with zero average response hours, which prospective buyers should interpret as a significant communication risk requiring direct verification of current operational status before placing orders.

The supplier profile does not disclose manufacturing capabilities, facility certifications, specific quality management systems, workforce size, revenue figures, or established client relationships. No ISO, GMP, or other quality system certifications are confirmed in the available data. Buyers are advised to request current business licence verification, active contact confirmation, and specific product quality documentation including certificate of analysis, material safety data sheet, and manufacturing batch records when evaluating this supplier for pharmaceutical intermediate procurement.
