Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 596.84 g/mol gives (R, R)-Astaxanthin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R, R)-Astaxanthin (CAS 60760-95-4), molecular formula C40H52O4 and molecular weight 596.84 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R, R)-Astaxanthin (C40H52O4) is characterized by a carboxylic acid group, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (R, R)-Astaxanthin 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.
