Description:
trans,trans-Muconic acid is an organic compound belonging to the class of dicarboxylic acids. It is an unsaturated, linear molecule with two carboxylic acid groups (–COOH) at each end of a conjugated diene system (two double bonds in the trans configuration). It is a white crystalline solid at room temperature and is soluble in water and polar organic solvents.

Uses:

1. Biodegradable Plastics: It is a key precursor in the production of bio-based plastics, such as polyamides and polyesters, due to its ability to polymerize.

2. Chemical Synthesis: Used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals.

3. Biotechnology: Produced through microbial fermentation as a sustainable alternative to petroleum-based chemicals.

4. Research: Studied for its potential applications in green chemistry and renewable materials.

Properties:

• Appearance: White crystalline solid

• Melting Point: ~300 °C (with decomposition)

• Solubility: Soluble in water, ethanol, and other polar solvents

• Acidity: pKa values around 4.0 and 5.0 (for the two carboxylic acid groups)

Safety Information:
trans,trans-Muconic acid is generally considered low in toxicity but should be handled with care. It may cause mild irritation to the skin, eyes, and respiratory system. Proper personal protective equipment (PPE), such as gloves, goggles, and a lab coat, should be worn when handling the compound. Avoid inhalation of dust and direct contact.
