Description
CATO supplies Diethyl 2-hydroxyterephthalate (CAS 74744-72-2), a certified reference material (molecular formula C12H14O5, MW 238.24 g/mol) for analytical method development and quality control.
Diethyl 2-hydroxyterephthalate (C12H14O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
As a certified reference material (CRM), Diethyl 2-hydroxyterephthalate 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.
