ECHEMI Editorial Reference

WHITE-TO-YELLOW CRYSTALS.
Benzoin is an organic compound with the formula PhCH(OH)C(O)Ph. It is a hydroxy ketone attached to two phenyl groups. It appears as off-white crystals, with a light camphor-like odor. Benzoin is synthesized from benzaldehyde in the benzoin condensation. It is chiral and it exists as a pair of enantiomers: (R)-benzoin and (S)-benzoin.
Benzoin is an off-white to yellow-white crystalline solid with an odor of camphor. Slightly acrid taste. When broken the fresh surfaces have a milky-white color. (NTP, 1992)|DryPowder|Solid|WHITE-TO-YELLOW CRYSTALS.|white to light yellow crystals with a faint, sweet, balsamic odour
Benzoin is an off-white to yellow-white crystalline solid with an odor of camphor. Slightly acrid taste. When broken the fresh surfaces have a milky-white color. (NTP, 1992)|Benzoin is a ketone that consists of acetophenone bearing hydroxy and phenyl substituents at the alpha-position. The parent of the class of benzoins. It has a role as an EC 3.1.1.1 (carboxylesterase) inhibitor. It is a member of benzoins and a secondary alpha-hydroxy ketone.|Benzoin is a white crystalline compound prepared by condensation of benzaldehyde in potassium cyanide, and is used in organic syntheses. This should not be confused with benzoin gum from STYRAX (see [DB11222]).
