Chemical Structure
Description
4-((2,5,6-Trimethylthieno[2,3-d]pyrimidin-4-yl)amino)benzoic acid hydrochloride (CAS 1179373-94-4), molecular formula C16H15N3O2SHCl and molecular weight 349.83 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((2,5,6-Trimethylthieno[2,3-d]pyrimidin-4-yl)amino)benzoic acid hydrochloride (C16H15N3O2SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-((2,5,6-Trimethylthieno[2,3-d]pyrimidin-4-yl)amino)benzoic acid hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
