Ethyl 2-amino-4-thioxo-1,4-dihydropyrimidine-5-carboxylate CAS 354788-58-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-amino-4-thioxo-1,4-dihydropyrimidine-5-carboxylate.

Ethyl 2-amino-4-thioxo-1,4-dihydropyrimidine-5-carboxylate (CAS 354788-58-2), molecular formula C7H9N3O2S and molecular weight 199.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 2-amino-4-thioxo-1,4-dihydropyrimidine-5-carboxylate (C7H9N3O2S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
