Properties: Deep-purple, hexagonal prisms from benzene + methanol. Red, rhombic, almost square leaflets from petr ether. mp 183° (evacuated tube). Absorption max (chloroform): 497, 466 nm. Less sol than a-carotene. Sol in CS2, benzene, chloroform. Moderately sol in ether, petr ether, oils. 100 ml hexane dissolve 109 mg at 0°. Very sparingly sol in methanol and ethanol. Practically insol in water, acids, alkalies. Dil solns are yellow. Absorbs oxygen from the air giving rise to inactive, colorless oxidation products. Keep tightly closed and protected from light. Store at low temp (-20°C). Commercial crystalline b-carotene has a vitamin A activity of 1.67 million U.S.P. units per gram. The I.U. of 0.6 mg b-carotene is almost exactly equivalent to 0.3 mg vitamin A.
Melting point: mp 183° (evacuated tube)
Absorption maximum: Absorption max (chloroform): 497, 466 nm
Use: Yellow coloring agent for foods.
Therap-Cat: Vitamin A precursor. Ultraviolet screen.
Therap-Cat-Vet: Vitamin A precursor for all species except cats.
