Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-2,4-dioxo-7-(propan-2-yl)-1h,2h,3h,4h-pyrido[2,3-d]pyrimidine-5-carboxylic acid.
1-Ethyl-2,4-dioxo-7-(propan-2-yl)-1h,2h,3h,4h-pyrido[2,3-d]pyrimidine-5-carboxylic acid (CAS 937691-16-2) is a high-purity analytical reference standard with the molecular formula C13H15N3O4 and a molecular weight of 277.28 g/mol.
The molecular framework of 1-Ethyl-2,4-dioxo-7-(propan-2-yl)-1h,2h,3h,4h-pyrido[2,3-d]pyrimidine-5-carboxylic acid (C13H15N3O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-Ethyl-2,4-dioxo-7-(propan-2-yl)-1h,2h,3h,4h-pyrido[2,3-d]pyrimidine-5-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.
