Chemical Structure

5α-Cholestane CAS CATO-CIM-105806 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5α-Cholestane.

CATO supplies 5α-Cholestane (CAS CATO-CIM-105806), a certified reference material (molecular formula C27H48, MW 372.67 g/mol) for analytical method development and quality control.

5α-Cholestane (C27H48) 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.

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

As a certified reference material (CRM), 5α-Cholestane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
