Chemical Structure
Description
2-(2,2-Difluoro-2H-1,3-benzodioxol-4-yl)acetic acid (CAS 531508-33-5) is a high-purity analytical reference standard with the molecular formula C9H6F2O4 and a molecular weight of 216.14 g/mol.
2-(2,2-Difluoro-2H-1,3-benzodioxol-4-yl)acetic acid (C9H6F2O4) 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-(2,2-Difluoro-2H-1,3-benzodioxol-4-yl)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.
