Chemical Structure

960589-81-5 C20H32O2 W1424 ent-17-Hydroxykauran-3-one CAS 960589-81-5 chemical structure

Description

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.

960589-81-5 C20H32O2 W1424 ent-17-Hydroxykauran-3-one (CAS 960589-81-5) is a high-purity analytical reference standard with the molecular formula C20H32O2 and a molecular weight of 304.47 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 960589-81-5 C20H32O2 W1424 ent-17-Hydroxykauran-3-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
