Chemical Structure
Description
As a certified reference material (CRM), 2-(4-Isopropylphenyl)-2-methylpropanoic 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-(4-Isopropylphenyl)-2-methylpropanoic acid (CAS 57438-45-6), a certified reference material (molecular formula C13H18O2, MW 206.28 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-Isopropylphenyl)-2-methylpropanoic acid (C13H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
