Chemical Structure
Description
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.
N-(5-bromo-1,3-thiazol-2-yl)cyclopropanecarboxamide (CAS 20415-77-4) is a high-purity analytical reference standard with the molecular formula C7H7BrN2OS and a molecular weight of 247.11 g/mol.
Based on its molecular formula C7H7BrN2OS, N-(5-bromo-1,3-thiazol-2-yl)cyclopropanecarboxamide contains an amide group, sulfur-containing functionality, 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 247.11 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.
