Chemical Structure
Description
5-Isopropyl-3-methylbenzofuran-2-carboxylic acid (CAS 1019109-33-1), molecular formula C13H14O3 and molecular weight 218.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Isopropyl-3-methylbenzofuran-2-carboxylic acid (C13H14O3) 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.
CATO manufactures 5-Isopropyl-3-methylbenzofuran-2-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
