The occurrence of all-trans-Retinyl Palmitate-d5 (Major) is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
all-trans-Retinyl Palmitate-d5 (Major) (CAS 1331666-45-5) is a high-purity analytical reference standard with the molecular formula C36H55D5O2 and a molecular weight of 529.89 g/mol.
Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, all-trans-Retinyl Palmitate-d5 (Major) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 529.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
