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 N-(5-bromo-1,3,4-thiadiazol-2-yl)-N-methylacetamide.
N-(5-bromo-1,3,4-thiadiazol-2-yl)-N-methylacetamide (CAS 64837-27-0) is a high-purity analytical reference standard with the molecular formula C5H6BrN3OS and a molecular weight of 236.09 g/mol.
Based on its molecular formula C5H6BrN3OS, N-(5-bromo-1,3,4-thiadiazol-2-yl)-N-methylacetamide contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
