Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 244.23 g/mol gives 3,5-Difluoro-2-(isopentyloxy)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,5-Difluoro-2-(isopentyloxy)benzoic acid (CAS 1443304-79-7), a certified reference material (molecular formula C12H14F2O3, MW 244.23 g/mol) for analytical method development and quality control.
3,5-Difluoro-2-(isopentyloxy)benzoic acid (C12H14F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, 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.
CATO manufactures 3,5-Difluoro-2-(isopentyloxy)benzoic 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.
