Chemical Structure

(all trans)-δ-Carotene CAS 472-92-4 chemical structure

Description

The occurrence of (all trans)-δ-Carotene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(all trans)-δ-Carotene (CAS 472-92-4), molecular formula C40H56 and molecular weight 536.87 g/mol, is a CATO reference standard with documented purity and traceability.

(all trans)-δ-Carotene (C40H56) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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.
