Chemical Structure
Description
As a certified reference material (CRM), (2-Chloro-5-cyclopropyl-4-methylphenyl)boronic 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.
CATO supplies (2-Chloro-5-cyclopropyl-4-methylphenyl)boronic acid (CAS 2225172-83-6), a certified reference material (molecular formula C10H12BClO2, MW 210.47 g/mol) for analytical method development and quality control.
(2-Chloro-5-cyclopropyl-4-methylphenyl)boronic acid (C10H12BClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
