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 Methyl (E)-3-(2-bromothiazol-4-yl)acrylate.
Methyl (E)-3-(2-bromothiazol-4-yl)acrylate (CAS 2786829-47-6), molecular formula C7H6BrNO2S and molecular weight 248.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H6BrNO2S, Methyl (E)-3-(2-bromothiazol-4-yl)acrylate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 248.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
