Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 204.09 g/mol gives 5-Bromo-4-cyclopropylthiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-4-cyclopropylthiazole (CAS 1243839-07-7) is a high-purity analytical reference standard with the molecular formula C6H6BrNS and a molecular weight of 204.09 g/mol.
The molecular framework of 5-Bromo-4-cyclopropylthiazole (C6H6BrNS) is characterized by a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
