Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2-amino-4-thien-2-yl-1,3-thiazol-5-yl)acetic acid hydrobromide (CAS 1156039-71-2) is a high-purity analytical reference standard with the molecular formula C9H8N2O2S2HBr and a molecular weight of 321.21 g/mol.
Based on its molecular formula C9H8N2O2S2HBr, (2-amino-4-thien-2-yl-1,3-thiazol-5-yl)acetic acid hydrobromide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 321.21 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.
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.
