Import 3-[(3-Amino-4-Methyla Minobenzoyl)Pyridin-2-Ylam — Buy in Bulk from Supplier in China

3-[(3-amino-4-methylaminobenzoyl)pyridin-2-ylamino]propionic acid is a fine chemical intermediate characterised by a complex heterocyclic-aromatic structure incorporating pyridine, benzamide, and propionic acid moieties. The compound is supplied by Shanghai Twisun Bio-Pharm Co., Ltd. for advanced chemical synthesis in pharmaceutical and biochemical research. Its molecular architecture, featuring multiple nitrogen-containing functional groups and a carboxylic acid terminus, provides diverse reactivity sites for peptide coupling, metal coordination, and heterocyclic derivatisation protocols.

The source description indicates the material is manufactured under quality control protocols to achieve elevated purity levels suitable for laboratory research and development use. The presence of both primary and secondary amine functionalities, together with the pyridine nitrogen and carboxylic acid group, creates a polyfunctional scaffold of interest for medicinal chemistry programmes targeting kinase inhibitors, DNA intercalators, and metal-based diagnostic agents. Standard handling requires protection from oxidation and moisture, as the aromatic amines are susceptible to air degradation and the free acid may facilitate intermolecular salt bridge formation affecting solubility profiles.

Primary end-users include pharmaceutical discovery laboratories, academic research groups in chemical biology, and agrochemical development teams requiring bespoke heterocyclic building blocks. The compound serves as a structural template for library synthesis or as a reference standard in analytical method development. Buyers should confirm with Shanghai Twisun Bio-Pharm Co., Ltd. the exact purity specification, residual solvent profile, and batch-to-batch variability data before committing to scale-up quantities, as these parameters are not stated in the available source information.

Shanghai Twisun Bio-Pharm Co., Ltd. operates from No.188 Jinou Road, Jinshan District, Shanghai 201512, China, placing it within the Shanghai chemical industry belt with access to port infrastructure and domestic logistics networks. The supplier carries an imported tier designation alongside harbour trust status, with a response rate of 0.00% and zero average response hours recorded on the platform. This combination of tier and engagement metrics indicates the profile may represent a trading intermediary or manufacturer with limited active platform management rather than direct export operations.

The company positions this product for pharmaceutical, agrochemical, and research laboratory markets, emphasising customisable supply quantities and regulatory compliance documentation. However, the source description contains no information about manufacturing facility GMP certification, synthetic route capability, analytical equipment, inventory holding, or dedicated quality assurance personnel. Buyers should request specific details on batch records, stability data, impurity profiling capabilities, and whether the company manufactures directly or sources from third-party producers before relying on this supplier for critical path synthesis programmes.
