<1-trans-Propenyl-cyclohexyl>-acetaldehyd, also known as 1-(trans-2-propenyl)cyclohexanecarbaldehyde, is an organic compound with the molecular formula C10H16O. It is a colorless to pale yellow liquid with a strong, pungent odor. This aldehyde is a derivative of cyclohexane, featuring a trans-propenyl group (CH2=CH-CH3) attached to the cyclohexane ring and an aldehyde functional group (-CHO) at the end of the propenyl chain. It is used as a fragrance ingredient in the perfume industry, particularly in the creation of floral and fruity scents, and as a flavoring agent in food and beverages. The compound is synthesized through various chemical reactions, such as the condensation of cyclohexanone with propionaldehyde, followed by reduction and oxidation steps. Due to its reactive nature, it is sensitive to light, heat, and air exposure, necessitating proper storage and handling conditions.
The CAS Registry Mumber 3915-40-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 5 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 3915-40: (6*3)+(5*9)+(4*1)+(3*5)+(2*4)+(1*0)=90 90 % 10 = 0 So 3915-40-0 is a valid CAS Registry Number.
