Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-4-chloro-6-oxo-1,6-dihydropyrimidine-5-carbonitrile.
2-Amino-4-chloro-6-oxo-1,6-dihydropyrimidine-5-carbonitrile (CAS 85840-23-9), molecular formula C5H3ClN4O and molecular weight 170.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Amino-4-chloro-6-oxo-1,6-dihydropyrimidine-5-carbonitrile (C5H3ClN4O) is characterized by an amide 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 2-Amino-4-chloro-6-oxo-1,6-dihydropyrimidine-5-carbonitrile 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.
