Description
TRANS-11-OCTADECENOIC ACID, also known as Vaccenic Acid, is a naturally occurring trans fatty acid found in various food sources, including meat and dairy products. It is structurally similar to conjugated linoleic acid (CLA) and has gained attention for its potential health benefits and applications.
Uses
Used in Antimicrobial Applications:
TRANS-11-OCTADECENOIC ACID is used as an antimicrobial agent for its activity against a variety of microorganisms. It is particularly effective against bacteria such as Escherichia coli, Micrococcus luteus, and Salmonella enteritidis, making it a valuable component in the development of natural antimicrobial solutions.
Used in Food Industry:
TRANS-11-OCTADECENOIC ACID is used as a natural preservative in the food industry to inhibit the growth of harmful microorganisms and extend the shelf life of perishable products. Its antimicrobial properties make it a suitable alternative to synthetic preservatives, promoting a healthier and more sustainable food system.
Used in Pharmaceutical Industry:
TRANS-11-OCTADECENOIC ACID is used as a potential therapeutic agent in the pharmaceutical industry due to its health benefits. Research suggests that it may have positive effects on cholesterol levels, blood sugar regulation, and immune function, making it a promising candidate for the development of new drugs and supplements.
Used in Cosmetics Industry:
TRANS-11-OCTADECENOIC ACID is used as an ingredient in cosmetics and personal care products for its moisturizing and skin-conditioning properties. It helps to maintain the skin's natural barrier, preventing moisture loss and promoting a healthy, hydrated complexion.
Purification Methods
Crystallise the acid from acetone (m 45-45.5o) or aqueous MeOH (m 43.5-43.7o). The methyl ester has b 174-175o/5mm. [B.eseken & Hoagland Rec Trav Chim, Pays Bas 46 632 1927, Ahmad et al. J Am Chem Soc 70 3391 1948, IR: Rao & Daubert J Am Chem Soc 70 1102 1948.]
Check Digit Verification of cas no
The CAS Registry Mumber 693-72-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 693-72:
(5*6)+(4*9)+(3*3)+(2*7)+(1*2)=91
91 % 10 = 1
So 693-72-1 is a valid CAS Registry Number.

The preparation of the monounsaturated fatty acid, trans-vaccenic acid 4 (TVA), using both Wittig and one-pot Julia-Kocieński olefination protocol, was achieved in good yield. Similarly a Wittig approach was employed for the stereoselective synthesis of cis-9-trans-11-conjugated linoleic acid 2 from trans-2-nonenal and (8-carboxyoctyl)triphenylphosphonium bromide 12.
