Chemical Structure
Description
The occurrence of cis-3-[2-(4-Bromophenyl)-2-oxoethyl]-cyclopentane-1-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
cis-3-[2-(4-Bromophenyl)-2-oxoethyl]-cyclopentane-1-carboxylic acid (CAS 733740-34-6), molecular formula C14H15BrO3 and molecular weight 311.17 g/mol, is a CATO reference standard with documented purity and traceability.
cis-3-[2-(4-Bromophenyl)-2-oxoethyl]-cyclopentane-1-carboxylic acid (C14H15BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), cis-3-[2-(4-Bromophenyl)-2-oxoethyl]-cyclopentane-1-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
