gamma-Polyglutamic Acid Sodium Salt (Technical Grade)(CAS: 26247-79-0)

Gamma-Polyglutamic Acid Sodium Salt (CAS: 26247-79-0) is a white to off-white powder. It has a high molecular weight and a high solubility in water. This compound exhibits good thermal stability and is slightly acidic. It reacts readily with bases and is resistant to hydrolysis under neutral and slightly acidic conditions. It has a pKa of approximately 4.5 to 5.0.

Gamma-Polyglutamic Acid Sodium Salt (CAS: 26247-79-0) is typically synthesized by the polymerization of L-glutamic acid using a condensation process. The reaction is usually catalyzed by amines such as diethylamine. The polymerization is carried out under mild conditions, and the product is then neutralized with sodium hydroxide to form the sodium salt.

Gamma-Polyglutamic Acid Sodium Salt (CAS: 26247-79-0) is widely used in the pharmaceutical industry for producing biocompatible materials and as a stabilizer. It is also used in the polymer industry for enhancing the properties of biodegradable polymers. Additionally, it finds applications in the food industry as a thickener and stabilizer, and in the biotechnology sector for immobilizing enzymes and other biological molecules.

When handling gamma-Polyglutamic Acid Sodium Salt (CAS: 26247-79-0), it is important to wear appropriate personal protective equipment (PPE), such as gloves and safety goggles. It should be stored in a cool, dry place away from direct sunlight and heat sources. In case of spills, use appropriate spill kits and follow the manufacturer's instructions for disposal.
