从China供应商批发进口5-Aminotetrazole — FOB条款

5-aminotetrazole (1H-tetrazol-5-amine, CAS 4418-61-5) is a heterocyclic organic compound with molecular formula C1H3N5, supplied by Hangzhou Sida Organic Chemical Co., Ltd. from their address at 376 Tianmushan Road, Hangzhou, Zhejiang Province. The material is characterised in the supplier's profile as a white crystalline powder with high purity, positioned for pharmaceutical synthesis and agrochemical production applications. The tetrazole ring structure with an exocyclic amino group provides both nucleophilic and weakly acidic properties, enabling its use as a versatile building block in medicinal chemistry and fine chemical synthesis.

The compound's heterocyclic architecture supports multiple reaction pathways including diazotisation, acylation, and condensation reactions for constructing more complex molecular architectures. Typical pharmaceutical applications leverage the tetrazole moiety as a bioisostere for carboxylic acid or amide functionalities, improving metabolic stability and membrane permeability in drug candidates. In agrochemical development, 5-aminotetrazole derivatives serve as precursors to herbicidal and fungicidal active ingredients. Standard material handling requires protection from moisture and strong oxidisers, with storage in tightly closed containers under ambient temperature conditions; specific stability data and reactivity hazards should be confirmed with the supplier for each intended application.

Buyers of this material span pharmaceutical contract research organisations, generic API manufacturers, agrochemical formulators, and university research laboratories investigating tetrazole-based energetic materials or novel heterocyclic scaffolds. The supplier indicates global trade in both bulk and research quantities, suggesting flexibility in order sizing. Payment and shipping terms are not specified in the available profile data and require direct negotiation with Hangzhou Sida Organic Chemical Co., Ltd. Prospective purchasers should confirm current pricing, minimum order quantities, lead times, and whether the supplier provides regulatory starting material documentation suitable for pharmaceutical filings.

Hangzhou Sida Organic Chemical Co., Ltd. operates from Room 301, Building Auxiliary, No. 376 Tianmushan Road, Hangzhou 310013, China, placing the company in Zhejiang Province's established chemical and pharmaceutical research corridor. The supplier holds a harbour trust tier classification, indicating a baseline level of platform engagement without premium verification. The response rate is recorded at 0.00% with zero average response hours, which constitutes a material communication risk that buyers must evaluate through independent due diligence before advancing transactions.

The available profile does not disclose manufacturing facility details, quality management system certifications, specific production capacities, employee numbers, annual revenues, or named client references. No ISO, GMP, or other third-party audit certifications are confirmed in the source data. The supplier's description emphasises the compound's applications but does not substantiate proprietary manufacturing expertise or differentiated quality control capabilities. Buyers should independently verify business licence validity, request facility audit reports, and confirm current operational status through direct engagement channels before relying on this supplier for critical raw material supply.
