Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,6-Dichloropyrido[3,2-d]pyrimidin-4(3H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO supplies 2,6-Dichloropyrido[3,2-d]pyrimidin-4(3H)-one (CAS 1036738-13-2), a certified reference material (molecular formula C7H3Cl2N3O, MW 216.02 g/mol) for analytical method development and quality control.
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.
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.
