Chemical Structure
Description
Structurally, Ethyl 2-chloro-4-(pyrazin-2-yl)thiazole-5-carboxylate (C10H8ClN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 269.71 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Ethyl 2-chloro-4-(pyrazin-2-yl)thiazole-5-carboxylate (CAS 1093114-57-8) is a high-purity analytical reference standard with the molecular formula C10H8ClN3O2S and a molecular weight of 269.71 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 2-chloro-4-(pyrazin-2-yl)thiazole-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.
