Description
As a certified reference material (CRM), (2E)-3-(1,3-Benzodioxol-5-yl)-2-propenoic acid 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 (2E)-3-(1,3-Benzodioxol-5-yl)-2-propenoic acid (CAS 38489-76-8), a certified reference material (molecular formula C10H8O4, MW 192.17 g/mol) for analytical method development and quality control.
(2E)-3-(1,3-Benzodioxol-5-yl)-2-propenoic acid (C10H8O4) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
