Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(chloromethyl)-5-ethyl-1,3,4-thiadiazole.
CATO supplies 2-(chloromethyl)-5-ethyl-1,3,4-thiadiazole (CAS 1461708-51-9), a certified reference material (molecular formula C5H7ClN2S, MW 162.64 g/mol) for analytical method development and quality control.
Structurally, 2-(chloromethyl)-5-ethyl-1,3,4-thiadiazole (C5H7ClN2S) contains a nitrile group, sulfur-containing functionality, chlorine 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 162.64 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.
