Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 311.17 g/mol gives cis-2-(4-Bromobenzoyl)cyclopentanecarboxylic acid methyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies cis-2-(4-Bromobenzoyl)cyclopentanecarboxylic acid methyl ester (CAS 791594-11-1), a certified reference material (molecular formula C14H15BrO3, MW 311.17 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H15BrO3, cis-2-(4-Bromobenzoyl)cyclopentanecarboxylic acid methyl ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
