7α-Hydroxystigmasterol CAS 64998-19-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

7α-Hydroxystigmasterol (CAS 64998-19-2) is a high-purity analytical reference standard with the molecular formula C29H48O2 and a molecular weight of 428.69 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 7α-Hydroxystigmasterol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.69 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).

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.
