Chemical Structure

all-trans-Retinyl Oleate CAS 631-88-9 chemical structure

Description

all-trans-Retinyl Oleate (CAS 631-88-9), molecular formula C38H62O2 and molecular weight 550.90 g/mol, is a CATO reference standard with documented purity and traceability.

all-trans-Retinyl Oleate (C38H62O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 all-trans-Retinyl Oleate 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.
