Description

N-(5-Methylisoxazol-3-yl)-2-(pyrazin-2-yl)thiazole-4-carboxamide (CAS 1235144-22-5), molecular formula C12H9N5O2S and molecular weight 287.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-(5-Methylisoxazol-3-yl)-2-(pyrazin-2-yl)thiazole-4-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.30 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.
