Ethyl Vanillin, CAS# 121-32-4, is a synthetic flavor agent derived from Vanillin, available as Fine white to slightly yellow crystal. Ethyl Vanillin has much stronger flavor than vanillin. It is widely used as aromas & perfumes in production of chocolate. Ethyl Vanillin is widely accepted as safe food additive in many countries. Vanillin is extracted from the vanilla beans but due to its low natural production and high demand it is prepared by various synthetic methods like chemical synthesis, enzymatic synthesis etc.1 Physiochemical properties of Vanillin: Vanillin is a white crystalline powder which has a melting point about 820C.

ortho-Vanillin, a compound of the formula C 8 H 8 O 3, is distinctly different from its more prevalent isomer, vanillin. The "ortho-" prefix refers to the position of the compound’s hydroxyl moiety, which is found in the para-position in vanillin. ortho-Vanillin is a fibrous, light-yellow, crystalline solid. Vanillin, as its name implies, is the major flavor component of vanilla. The three oxygen atoms in this small aromatic compound are in different functional groups: alcohol, aldehyde, and ether. It is a white crystalline solid with a melting point of 81–83 ºC.

Ethyl vanillin: white to pale yellow crystal; melting 76.5 C; having 3.5 times stronger flavour and more stable in organic solvents and in storage than vanillin but does not have the true flavour. It is used in pharmaceutical preparations and the food industry as a flavoring agent to replace or strengthen vanilla. 260960 ; The DNA-PK Inhibitor, also referenced under CAS 20357-25-9, controls the biological activity of DNA-PK.
