5-Chloro-1,3-dimethyl-1H,2H,3H,4H-pyrido[2,3-d]pyrimidine-2,4-dione CAS 112734-83-5

Description

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 supplies 5-Chloro-1,3-dimethyl-1H,2H,3H,4H-pyrido[2,3-d]pyrimidine-2,4-dione (CAS 112734-83-5), a certified reference material (molecular formula C9H8ClN3O2, MW 225.63 g/mol) for analytical method development and quality control.

Based on its molecular formula C9H8ClN3O2, 5-Chloro-1,3-dimethyl-1H,2H,3H,4H-pyrido[2,3-d]pyrimidine-2,4-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
