Chemical Structure
Description
As a certified reference material (CRM), Ethyl 2-(2-acetylhydrazinyl)-4-methylthiazole-5-carboxylate 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 Ethyl 2-(2-acetylhydrazinyl)-4-methylthiazole-5-carboxylate (CAS 98840-82-5), a certified reference material (molecular formula C9H13N3O3S, MW 243.28 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-(2-acetylhydrazinyl)-4-methylthiazole-5-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.28 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.
