Chemical Structure
Description
4-Amino-6-thioxo-1,6-dihydropyrimidine-5-carbaldehyde (CAS 155087-62-0), molecular formula C5H5N3OS and molecular weight 155.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Amino-6-thioxo-1,6-dihydropyrimidine-5-carbaldehyde (C5H5N3OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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-Amino-6-thioxo-1,6-dihydropyrimidine-5-carbaldehyde 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.
