Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(5-Chloro-1,3,4-thiadiazol-2-yl)methanamine (CAS 1935236-26-2) is a high-purity analytical reference standard with the molecular formula C3H4ClN3S and a molecular weight of 149.60 g/mol.
Based on its molecular formula C3H4ClN3S, (5-Chloro-1,3,4-thiadiazol-2-yl)methanamine contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 149.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
