Chemical Structure

Dihydrolanosterol CAS 79-62-9 chemical structure

Description

Dihydrolanosterol (CAS 79-62-9), molecular formula C30H52O and molecular weight 428.73 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Dihydrolanosterol (C30H52O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
