Chemical Structure

3,5-Difluoro-4-(oxan-4-ylmethoxy)benzoic acid CAS 1283981-13-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,5-Difluoro-4-(oxan-4-ylmethoxy)benzoic acid.

3,5-Difluoro-4-(oxan-4-ylmethoxy)benzoic acid (CAS 1283981-13-4) is a high-purity analytical reference standard with the molecular formula C13H14F2O4 and a molecular weight of 272.24 g/mol.

The molecular framework of 3,5-Difluoro-4-(oxan-4-ylmethoxy)benzoic acid (C13H14F2O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 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 3,5-Difluoro-4-(oxan-4-ylmethoxy)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.
