(9E,11Z)-9,11-Octadecadienoic acid(CAS: 2420-56-6)

(9E,11Z)-9,11-Octadecadienoic acid, also known as conjugated linoleic acid (CLA), is a positional and geometric isomer of linoleic acid. It is a fatty acid with a molecular formula of C18H34O2. CLA is characterized by its unique double bonds in the 9 and 11 positions, which make it a conjugated fatty acid. It is naturally found in trace amounts in beef and dairy products and is also synthesized in the human body from linoleic acid.

(9E,11Z)-9,11-Octadecadienoic acid is primarily used in the food industry as a nutritional supplement due to its potential health benefits, such as improving body composition and supporting immune function. It is also utilized in the pharmaceutical industry for its potential anti-inflammatory and anti-cancer properties. Additionally, it has applications in cosmetics and research for studying lipid metabolism and fatty acid biology.

While (9E,11Z)-9,11-Octadecadienoic acid is generally considered safe for human consumption, it is important to follow recommended dosages. Toxicity studies have shown that high doses may cause adverse effects, such as liver damage and kidney function impairment. Handling the compound should be done with care, wearing appropriate personal protective equipment (PPE) like gloves and goggles. Storage and handling must comply with safety standards to prevent inhalation and skin contact.

(9E,11Z)-9,11-Octadecadienoic acid should be stored in a cool, dry place away from direct sunlight and moisture to maintain its stability. Optimal storage conditions include a temperature range of 15-25°C (59-77°F) and a relative humidity below 60%. The compound should be kept in a tightly sealed container to prevent oxidation. It is advisable to store it in a refrigerator (2-8°C) to extend its shelf life and prevent degradation. Avoid contact with incompatible materials, such as strong acids and bases.
