Pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione CAS 21038-66-4

Description

The occurrence of Pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (CAS 21038-66-4), a certified reference material (molecular formula C7H5N3O2, MW 163.13 g/mol) for analytical method development and quality control.

The molecular framework of Pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (C7H5N3O2) is characterized by an amino-acid-derived structure, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione 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.
