It can be used as a raw material to synthesize the following ingredients:Supplement

Succinic acid is used as a supplement for people who want to lose weight quickly by burning fat instead of carbohydrates for energy usage during exercise. Some researchers have shown that succinic acid can be an effective treatment for fatigue associated with physical activity especially during long distance running events like marathons or triathlons where athletes are required to perform at their peak performance levels for several hours continuously until they reach the finish line. This supplement has been shown to increase endurance performance by helping your body burn fat instead of carbohydrates for energy production during exercise sessions.

Industrial Applications

Succinic acid is used in many branches of the chemical industry (e.g., for production of plastics, detergents and pharmaceuticals). In addition to its use as an industrial intermediate, succinic acid is used by the food industry as a flavoring agent and flavor enhancer (e.g., in potato chips). Succinic acid can be added to foods as a preservative against molds and yeasts. It is also used in pharmaceuticals and cosmetics (e.g., soaps).

These are its derivatives.


As a buffering and masking agent, this acid is used in cosmetics and personal care products. According to Roquette, a supplier of biosuccinic acid, this ingredient has antimicrobial properties, acne treatment, antioxidant activity, and many other properties.

What is the health benefits of succinic acid?

Succinic acid is a natural, non-essential amino acid. It is an intermediate in the catabolism of lysine and arginine and is found in plants, animals, and humans.

The most important health benefit of succinic acid is its ability to act as an antioxidant. Succinic acid has been shown to have potent anti-inflammatory properties, which may help alleviate symptoms associated with Crohn’s disease, ulcerative colitis, rheumatoid arthritis, and other inflammatory diseases.

In addition to acting as an antioxidant, succinic acid can also help increase energy production in cells by activating complex I of the electron transport chain.

Is succinic acid safe to eat?

Succinic acid is a weak organic acid that is found in many foods and in our bodies. It is also used as a food additive to enhance the flavor of meat products, and it can be used as a preservative.

Succinic Acid Safety Information

The U.S. Food and Drug Administration (FDA) has given succinic acid GRAS status (Generally Recognized As Safe). This means that it has been shown to be safe when eaten at levels up to 5 mg/kg body weight per day. However, there are some concerns about the safety of this additive.

In 2005, scientists at the University of California, Davis reported that rats fed high doses of succinic acid had an increased risk of developing tumors in their kidneys and livers compared to control animals that were not fed any succinic acid.


In food, succinic acid is generally recognized as safe (GRAS) and can be used to enhance flavor and to modify pH levels at levels that do not exceed accepted manufacturing practices. Its applications have been approved for condiments and relishes, with a maximum usage rate of 0.084% and 0.0061% for meat products.


A food additive, succinic acid (E363), has been listed in Regulation (EU) No 231/2012 as an authorised additive that falls

What is the side effects of succinic acid?

Succinic acid is a type of amino acid, a building block for proteins. It is found in many foods and can be taken as a dietary supplement.

Too much succinic acid may cause:Is succinic acid soluble in water?

Succinic acid is a carboxylic acid, with the chemical formula C4H6O4. It is a colorless solid, soluble in water, ethanol, diethyl ether and glycerol.

Succinic acid is naturally present in many foods and food products. It is found in milk, cheese, yogurt and meat products. It is also added to processed foods as a flavor enhancer or preservative.

Succinic acid is used in many industries including the production of cosmetics, pharmaceuticals, plastics and food additives such as artificial sweeteners.

Is succinic acid organic or inorganic?

Succinic acid is a naturally occurring organic compound that is also used to make many other chemicals. It is found in nature as a component of many foods, including cheese and soy sauce. It can be made by fermenting various types of carbohydrates.

In the industrial production process, succinic acid is produced by adding water to maleic anhydride, which comes from petroleum or coal tar. This process produces carbon dioxide and methane as waste products.

Is succinic acid polar or nonpolar?

The answer to the question “Is succinic acid polar or nonpolar?” is that succinic acid is an amphoteric molecule. This means that it can act as either a base or an acid. The reason for this is because of the presence of an acidic hydrogen on one end and a basic nitrogen on another end.

Succinic acid forms salts with both acids and bases, depending on how you look at it. The succinate ion (which has two carbons attached) forms salts with bases like sodium hydroxide and ammonium hydroxide. These salts are called alkali metal salts, which means they dissolve in water readily and are good electrolytes, meaning they conduct electricity well. On the other hand, when succinic acid loses its proton (H+) and becomes negatively charged (CHCOO–), it forms salts with acids like hydrochloric acid (HCl). These salts are called hydrates, which means they don’t dissolve in water very well at all!

Is succinic acid saturated or unsaturated?

Succinic acid is an organic compound with the formula (CH3)2COCH=CHCO2H. It is a dicarboxylic acid. The conjugate base of succinic acid is called succinate, and the salt of succinate and hydrochloric acid is known as monosodium succinate.

It occurs naturally in plants, animals and microorganisms where it plays an important role in the Krebs cycle to produce energy. In industry it is produced by fermentation of sugars or carbohydrates, followed by purification; or by steam cracking of butane into ethylene and propylene.
