Chemical Structure
Description
(1s)-1-(2,3-Dihydro-1-benzofuran-5-yl)ethan-1-ol (CAS 1344939-13-4), molecular formula C10H12O2 and molecular weight 164.20 g/mol, is a CATO reference standard with documented purity and traceability.
(1s)-1-(2,3-Dihydro-1-benzofuran-5-yl)ethan-1-ol (C10H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
