Description
As a certified reference material (CRM), 1,3-Dimethoxy-1,3-dihydroisobenzofuran 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 1,3-Dimethoxy-1,3-dihydroisobenzofuran (CAS 24388-70-3), a certified reference material (molecular formula C10H12O3, MW 180.20 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H12O3, 1,3-Dimethoxy-1,3-dihydroisobenzofuran contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 180.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
