Chemical Structure

(3alpha,5beta,6beta,7alpha)-6-Ethylcholane-3,7,24-triol CAS 1632118-70-7 chemical structure

Description

(3alpha,5beta,6beta,7alpha)-6-Ethylcholane-3,7,24-triol (CAS 1632118-70-7) is a high-purity analytical reference standard with the molecular formula C26H46O3 and a molecular weight of 406.64 g/mol.

Structurally, (3alpha,5beta,6beta,7alpha)-6-Ethylcholane-3,7,24-triol (C26H46O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 406.64 g/mol, it falls into the moderately-high-molecular-weight range. 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.
