Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Bromo-1,2,3-thiadiazole (CAS 500314-99-8) is a high-purity analytical reference standard with the molecular formula C2HBrN2S and a molecular weight of 165.01 g/mol.
Owing to a nitrile group, sulfur-containing functionality, bromine substitution, 4-Bromo-1,2,3-thiadiazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 165.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4-Bromo-1,2,3-thiadiazole 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.
