Chemical Structure
Description
2-Chloro-N-(6-methyl-7-oxo-8,8a-dihydro-7H-thiazolo[3,2-b][1,2,4]triazin-3-yl)acetamide (CAS 1256627-72-1), molecular formula C8H9ClN4O2S and molecular weight 260.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-N-(6-methyl-7-oxo-8,8a-dihydro-7H-thiazolo[3,2-b][1,2,4]triazin-3-yl)acetamide (C8H9ClN4O2S) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 260.70 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures 2-Chloro-N-(6-methyl-7-oxo-8,8a-dihydro-7H-thiazolo[3,2-b][1,2,4]triazin-3-yl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
