Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(1<I>R</I>,2<I>S</I>,5<I>R</I>)-(-)-menthol (<I>S</I>)-pair Toluene sulfinate (CAS 1517-82-4) is a high-purity analytical reference standard with the molecular formula C17H32O2S and a molecular weight of 300.50 g/mol.

(1<I>R</I>,2<I>S</I>,5<I>R</I>)-(-)-menthol (<I>S</I>)-pair Toluene sulfinate (C17H32O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

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.
