Glutinous rice

Glutinic acid is a chemical compound that belongs to the class of organic compounds known as carboxylic acids. It is also known as pentanedioic acid due to its structural similarity to pentane, with two carboxyl groups replacing two of the hydrogen atoms.

Chemical Structure

Glutinic acid has the chemical formula C5H8O4. It consists of a five-carbon alkane chain, with a carboxyl group (COOH) at each end. This structure is reflected in its systematic name, pentanedioic acid, which indicates a five-carbon chain (pentane) with two carboxyl groups (dioic acid).

Properties

Glutinic acid is a white, crystalline solid at room temperature. It is soluble in water and can be dissolved in various organic solvents. It has a strong acidic taste and is non-toxic. The acid is a dibasic acid, meaning it can donate two protons per molecule in solution.

Synthesis

Glutinic acid can be synthesized through the oxidation of cyclopentanol or cyclopentanone with potassium permanganate. It can also be produced from the oxidation of glutaryl chloride with water.

Uses

Glutinic acid is used in the manufacture of plasticizers, resins, dyes, and pharmaceuticals. It is also used as a laboratory reagent in various chemical reactions.

Safety

As with all carboxylic acids, glutinic acid should be handled with care. It can cause burns and eye damage, and its dust can cause respiratory irritation.
