Chemical Structure
Description
2-(bromomethyl)-5-methyl-1,3,4-thiadiazole (CAS 75341-29-6), molecular formula C4H5BrN2S and molecular weight 193.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(bromomethyl)-5-methyl-1,3,4-thiadiazole (C4H5BrN2S) 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 193.06 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
