Chemical Structure

Cholesteryl n-butyrate CAS 521-13-1 chemical structure

Description

CATO manufactures Cholesteryl n-butyrate 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.

CATO supplies Cholesteryl n-butyrate (CAS 521-13-1), a certified reference material (molecular formula C31H52O2, MW 456.74 g/mol) for analytical method development and quality control.

Structurally, Cholesteryl n-butyrate (C31H52O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 456.74 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.
