Undecanoyl 4-hydroxybenzoate, also known as undecyl p-hydroxybenzoate, is a chemical compound with the molecular formula C18H26O3. It is a derivative of 4-hydroxybenzoic acid, where the hydroxyl group is esterified with undecyl alcohol, resulting in an ester compound. This organic compound is commonly used as a preservative in cosmetics, pharmaceuticals, and personal care products due to its antimicrobial properties. It helps to prevent the growth of bacteria, yeasts, and molds, thereby extending the shelf life of these products. Additionally, undecyl 4-hydroxybenzoate is known for its low toxicity and minimal skin irritation, making it a safe and effective preservative option.

69679-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69679-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,6,7 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69679-31:
(7*6)+(6*9)+(5*6)+(4*7)+(3*9)+(2*3)+(1*1)=188
188 % 10 = 8
So 69679-31-8 is a valid CAS Registry Number.

New Liquid Crystal Compounds: (+)-4-Alkoxycarbonylphenyl-4-benzoate

Haramoto, Y.,Kamogawa, H.

, p. 161 - 166 (2007/10/02)

New Liquid Crystal Compounds: (+)-4-Alkoxycarbonylphenyl-4-benzoates (5) were synthesized.The mesomorphic behavior of these compounds is compared with that of (+)-4-(2-methylbutyloxycarbonyl)phenyl 4-(5-alkyl-1,3-dioxan-2-yl)benzoates (6).Compounds 5 exhibited cholesteric and smectic A phases and their transition temperatures to the isotropic state were lower than those of corresponding compounds 6.These properties are supposed to originate in the greater molecular widths of the formers caused by 2-methylbutyl group at the 5 position of the 1,3-dioxane ring.Though compounds 6 exhibit the ferroelectric behavior, compounds 5 don't.This might mean that a short distance between the carbonyl and chiral group is one factor for the appearance of the SmC* phase.
