Chemical Structure

beta-Sitosterol CAS 83-46-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 414.71 g/mol gives beta-Sitosterol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

beta-Sitosterol (CAS 83-46-5), molecular formula C29H50O and molecular weight 414.71 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of beta-Sitosterol (C29H50O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures beta-Sitosterol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
