Chemical Structure
Description
28368-06-1 Decaprenoxanthin (2R,6R,2'R,6'R)-2,2-Bis(4-hydroxy-3-methyl-2-butenyl)-epsilon,epsilon-carotene (CAS 28368-06-1), molecular formula C50H72O2 and molecular weight 705.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 28368-06-1 Decaprenoxanthin (2R,6R,2'R,6'R)-2,2-Bis(4-hydroxy-3-methyl-2-butenyl)-epsilon,epsilon-carotene (C50H72O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
