Chemical Structure
Description
As a certified reference material (CRM), methyl 4-fluoro-3-hydroxybenzoate 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.
CATO supplies methyl 4-fluoro-3-hydroxybenzoate (CAS 214822-96-5), a certified reference material (molecular formula C8H7FO3, MW 170.14 g/mol) for analytical method development and quality control.
methyl 4-fluoro-3-hydroxybenzoate (C8H7FO3) 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.
