Description

As a certified reference material (CRM), 2-Chloro-8-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidine-3-carbaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies 2-Chloro-8-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidine-3-carbaldehyde (CAS 303024-75-1), a certified reference material (molecular formula C10H7ClN2O2, MW 222.63 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-8-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidine-3-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
