Description

CATO supplies 3-Ethyl-2-(4-methylthiazol-2-yl)-4H-pyrido[1,2-a]pyrimidin-4-one (CAS 918891-49-3), a certified reference material (molecular formula C14H13N3OS, MW 271.34 g/mol) for analytical method development and quality control.

Structurally, 3-Ethyl-2-(4-methylthiazol-2-yl)-4H-pyrido[1,2-a]pyrimidin-4-one (C14H13N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 271.34 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 3-Ethyl-2-(4-methylthiazol-2-yl)-4H-pyrido[1,2-a]pyrimidin-4-one 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.
