Chemical Structure
Description
CATO supplies (1R,3S)-3-(2-(3-bromophenyl)-2-oxoethyl)cyclopentane-1-carboxylic acid (CAS 733740-33-5), a certified reference material (molecular formula C14H15BrO3, MW 311.17 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, (1R,3S)-3-(2-(3-bromophenyl)-2-oxoethyl)cyclopentane-1-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), (1R,3S)-3-(2-(3-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.
