Chemical Structure

5 β-Stigmastane CAS 4705-29-7 chemical structure

Description

5 β-Stigmastane (C29H52) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

5 β-Stigmastane (CAS 4705-29-7) is a high-purity analytical reference standard with the molecular formula C29H52 and a molecular weight of 400.72 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.

CATO manufactures 5 β-Stigmastane 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.
