Chemical Structure
Description
1,3,4-Thiadiazole-2-carbonyl chloride (CAS 104473-08-7), molecular formula C3HClN2OS and molecular weight 148.57 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3,4-Thiadiazole-2-carbonyl chloride (C3HClN2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 148.57 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 1,3,4-Thiadiazole-2-carbonyl chloride 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.
