Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,3-Difluoro-2-hydroxy-2-methylpropanoic acid (CAS 1869-40-5) is a high-purity analytical reference standard with the molecular formula C4H6F2O3 and a molecular weight of 140.09 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 3,3-Difluoro-2-hydroxy-2-methylpropanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.09 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.
CATO manufactures 3,3-Difluoro-2-hydroxy-2-methylpropanoic 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.
