Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 209.00 g/mol gives 2,5-Dichloro-4-fluorobenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,5-Dichloro-4-fluorobenzoic acid (CAS 35989-28-7), molecular formula C7H3Cl2FO2 and molecular weight 209.00 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2,5-Dichloro-4-fluorobenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2,5-Dichloro-4-fluorobenzoic 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.
