Chemical Structure
Description
As a certified reference material (CRM), 2-((3AR,7aS)-2,2-dimethyl-3a,7a-dihydrobenzo[d][1,3]dioxol-5-yl)ethan-1-ol 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.
2-((3AR,7aS)-2,2-dimethyl-3a,7a-dihydrobenzo[d][1,3]dioxol-5-yl)ethan-1-ol (CAS 1998128-17-8), molecular formula C11H16O3 and molecular weight 196.24 g/mol, is a CATO reference standard with documented purity and traceability.
2-((3AR,7aS)-2,2-dimethyl-3a,7a-dihydrobenzo[d][1,3]dioxol-5-yl)ethan-1-ol (C11H16O3) 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.
