Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 600.87 g/mol gives β-Carotenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies β-Carotenone (CAS 20126-74-3), a certified reference material (molecular formula C40H56O4, MW 600.87 g/mol) for analytical method development and quality control.
The molecular framework of β-Carotenone (C40H56O4) 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.
