Chemical Structure

Rubixanthin CAS 3763-55-1 chemical structure

Description

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.

Rubixanthin (CAS 3763-55-1), molecular formula C40H56O and molecular weight 552.87 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, Rubixanthin is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 552.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Rubixanthin 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.
