Chemical Structure
Description
Structurally, 6-(4-Bromophenyl)-3,5-dimethylimidazo[2,1-b]thiazole-2-carboxylic acid (C14H11BrN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 351.22 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
6-(4-Bromophenyl)-3,5-dimethylimidazo[2,1-b]thiazole-2-carboxylic acid (CAS 1181348-05-9), molecular formula C14H11BrN2O2S and molecular weight 351.22 g/mol, is a CATO reference standard with documented purity and traceability.
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.
