Appearance/Colour :Yellow crystals or orange solid
Melting Point: 62-64oC
Boiling Point: 421.2 °C at 760 mmHg
Flash Point:147.3 °C
Density: 0.954 g/cm3
Solubility:All retinol esters are practically insoluble in water, soluble or partly soluble in anhydrous ethanol and miscible with organic solvents. Vitamin A and its esters are very sensitive to the action of air, oxidising agents, acids, light and heat. Carry out the assay and all tests as rapidly as possible, avoiding exposure to actinic light and air, oxidising agents, oxidation catalysts (e.g. copper , iron), acids and heat; use freshly prepared solutions.
