Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7448-02-4 14-demethyllanosterol 4,4-dimethyl-5alpha-cholesta-8,24-dien-3beta-ol 4,4-dimethylzymosterol (3beta,5alpha)-4,4-dimethylcholesta-8,24-dien-3-ol 14-desmethyllanosterol 4,4-dimethylcholesta-8(9),24-dien-3beta-ol 4,4-Dimethyl-8,24-cholestadienol CHEBI:18364.

7448-02-4 14-demethyllanosterol 4,4-dimethyl-5alpha-cholesta-8,24-dien-3beta-ol 4,4-dimethylzymosterol (3beta,5alpha)-4,4-dimethylcholesta-8,24-dien-3-ol 14-desmethyllanosterol 4,4-dimethylcholesta-8(9),24-dien-3beta-ol 4,4-Dimethyl-8,24-cholestadienol CHEBI:18364 (CAS 7448-02-4), molecular formula C29H48O and molecular weight 412.69 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 7448-02-4 14-demethyllanosterol 4,4-dimethyl-5alpha-cholesta-8,24-dien-3beta-ol 4,4-dimethylzymosterol (3beta,5alpha)-4,4-dimethylcholesta-8,24-dien-3-ol 14-desmethyllanosterol 4,4-dimethylcholesta-8(9),24-dien-3beta-ol 4,4-Dimethyl-8,24-cholestadienol CHEBI:18364 (C29H48O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 412.69 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.
