Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Aminothieno[2,3-d]pyrimidine-6-carboxylic acid.
2-Aminothieno[2,3-d]pyrimidine-6-carboxylic acid (CAS 1780922-44-2) is a high-purity analytical reference standard with the molecular formula C7H5N3O2S and a molecular weight of 195.20 g/mol.
The molecular framework of 2-Aminothieno[2,3-d]pyrimidine-6-carboxylic acid (C7H5N3O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 2-Aminothieno[2,3-d]pyrimidine-6-carboxylic acid 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.
