Chemical Structure
Description
As a certified reference material (CRM), 2-Hydroxyethyl 4-methylbenzoate 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 2-Hydroxyethyl 4-methylbenzoate (CAS 28129-15-9), a certified reference material (molecular formula C10H12O3, MW 180.20 g/mol) for analytical method development and quality control.
2-Hydroxyethyl 4-methylbenzoate (C10H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
