A fat-soluble vitamin (retinol and its derivatives) essential for vision, growth, skin and immune defences; it was discovered in 1913 and its chemical structure was described in 1931 by chemist Paul Karrer. This family brings together pharmacopoeial impurities, labelled standards and other impurities.
