Chemical Structure

Brassicasterol CAS 474-67-9 chemical structure

Description

Brassicasterol (CAS 474-67-9), molecular formula C28H46O and molecular weight 398.66 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, Brassicasterol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
