Description
CATO manufactures 3,5-Dibromo-1,2,4-thiadiazole 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.
CATO supplies 3,5-Dibromo-1,2,4-thiadiazole (CAS 213325-84-9), a certified reference material (molecular formula C2Br2N2S, MW 243.91 g/mol) for analytical method development and quality control.
Structurally, 3,5-Dibromo-1,2,4-thiadiazole (C2Br2N2S) contains a nitrile group, sulfur-containing functionality, bromine 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 243.91 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.
