Description
CATO manufactures 2,2-Difluoro-2-(methylsulfonyl)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.
2,2-Difluoro-2-(methylsulfonyl)acetic acid (CAS 1505023-53-9), molecular formula C3H4F2O4S and molecular weight 174.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, an ether linkage, fluorine substitution, 2,2-Difluoro-2-(methylsulfonyl)acetic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
