Isononanoic Acid

3,5,5-Trimethylhexanoic acid, also known as Isononanoic acid or IC9, is an organic compound with the chemical formula C9H18O2. It consists of a nine-carbon chain with three methyl groups (CH3) attached to the fifth carbon atom, hence the name 3,5,5-trimethylhexanoic acid. It belongs to the class of carboxylic acids and is characterized by its branched molecular structure. Isononanoic acid is a clear, colorless liquid with a faint odor and soluble in usual organic solvents.

Frequently Asked Questions About IC9

What are the Applications of IC9?

• Isononanoic acid is used in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals
• This acid is utilized in the production of coatings, adhesives, and sealants
• Isononanoic acid can be used as a plasticizer
• Due to its unique odor profile, Isononanoic acid is also employed in the fragrance and flavor industry
• It can be employed as a building block for the production of esters, polymers, and other organic compounds

What are the Physical Properties of Isononanoic Acid?

Isononanoic acid is a colorless liquid with a strong, pungent odor. It has a relatively high boiling point of around 165-170 degrees Celsius (329-338 degrees Fahrenheit) and a moderate melting point of approximately -10 degrees Celsius (14 degrees Fahrenheit).

How is the Solubility of Isononanoic Acid?

Isononanoic acid (3,5,5-trimethylhexanoic acid) is sparingly soluble in water. It is classified as a hydrophobic or lipophilic compound due to its long hydrocarbon chain. The carboxylic acid group (-COOH) contributes to its limited solubility in water. However, isononanoic acid is more soluble in organic solvents such as ethanol, methanol, acetone, and chloroform. Its solubility in these organic solvents is higher due to the affinity between the nonpolar hydrocarbon chain and the nonpolar nature of the solvents.

How is the Chemical Reactivity of Isononanoic Acid?

Isononanoic acid is a carboxylic acid that exhibits typical acidic properties. It can donate a proton (H+) from its carboxyl group, allowing it to participate in acid-base reactions. It undergoes esterification reactions to form esters and can react with metals to form metal carboxylates or salts.

What are the Derivatives of Isononanoic Acid?

3,5,5-Trimethylhexanoic acid (isonoanoic acid or pivalic acid) can undergo various chemical reactions and transformations, leading to the formation of several derivatives. Some of the common derivatives of isonoanoic acid include:

1. Esters: Isonoanoic acid can form esters through esterification reactions. Esters of isonoanoic acid are widely used in industries such as flavors, fragrances, and plastics. Examples of isonoanoic acid esters include isopropyl isonoanoate, ethyl isonoanoate, and methyl isonoanoate.
2. Amides: By reacting isonoanoic acid with amines, amides can be formed. These amides find applications in various fields, including pharmaceuticals, polymers, and surfactants.
3. Anhydrides: Isonoanoic acid can undergo dehydration to form anhydrides, such as isonoanoic anhydride. Anhydrides are utilized in organic synthesis reactions and as catalysts in polymerization processes.
