Chemical Structure
Description
2-((4-(Difluoromethoxy)-3-methoxybenzyl)thio)acetic acid (CAS 923149-01-3), molecular formula C11H12F2O4S and molecular weight 278.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((4-(Difluoromethoxy)-3-methoxybenzyl)thio)acetic acid (C11H12F2O4S) is characterized by a sulfone group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-((4-(Difluoromethoxy)-3-methoxybenzyl)thio)acetic 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.
