β-Carotene 5,6-epoxide CAS 1923-89-3 chemical structure

Description

CATO manufactures β-Carotene 5,6-epoxide 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.

β-Carotene 5,6-epoxide (CAS 1923-89-3) is a high-purity analytical reference standard with the molecular formula C40H56O and a molecular weight of 552.87 g/mol.

The molecular framework of β-Carotene 5,6-epoxide (C40H56O) is characterized by a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
