Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 178.23 g/mol gives 4-(Butan-2-yl)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(Butan-2-yl)benzoic acid (CAS 40912-38-7), a certified reference material (molecular formula C11H14O2, MW 178.23 g/mol) for analytical method development and quality control.
4-(Butan-2-yl)benzoic acid (C11H14O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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), 4-(Butan-2-yl)benzoic 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.
