Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-methyl-1,3,4-thiadiazole-2-sulfonyl fluoride.
5-methyl-1,3,4-thiadiazole-2-sulfonyl fluoride (CAS 1909313-52-5) is a high-purity analytical reference standard with the molecular formula C3H3FN2O2S2 and a molecular weight of 182.20 g/mol.
Structurally, 5-methyl-1,3,4-thiadiazole-2-sulfonyl fluoride (C3H3FN2O2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 182.20 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).
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 5-methyl-1,3,4-thiadiazole-2-sulfonyl fluoride 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.
