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.
1-[4-Amino-2-(methylthio)-5-thiazolyl]ethanone (CAS 39736-26-0), molecular formula C6H8N2OS2 and molecular weight 188.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1-[4-Amino-2-(methylthio)-5-thiazolyl]ethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.27 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).
As a certified reference material (CRM), 1-[4-Amino-2-(methylthio)-5-thiazolyl]ethanone 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.
