Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 2,3,4-trifluoro-5-methoxybenzoate (CAS 38233-46-4) is a high-purity analytical reference standard with the molecular formula C9H7F3O3 and a molecular weight of 220.15 g/mol.
Methyl 2,3,4-trifluoro-5-methoxybenzoate (C9H7F3O3) 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).
As a certified reference material (CRM), Methyl 2,3,4-trifluoro-5-methoxybenzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
