Chemical Structure

α-Spinasterol CAS 481-18-5 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, α-Spinasterol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.69 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.

α-Spinasterol (CAS 481-18-5) is a high-purity analytical reference standard with the molecular formula C29H48O and a molecular weight of 412.69 g/mol.

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.
