Uses and synthesis of L-Pyroglutamic acid powder

L-Pyroglutamic acid powder is also known as L-pyroglutamic acid, L-pyroglutamic acid, L-Pyroglutamic acid CAS 98-79-3 is a colourless orthorhombic bipyramidal crystal precipitated from a mixture of ethanol and petroleum ether, with a melting point of 162～163°C. L-Pyroglutamic acid Raw Materials Soluble in water, alcohol, acetone and glacial acetic acid, slightly soluble in ethyl acetate, insoluble in ether.

Applications / Functions of L-Pyroglutamic acid powder

• L-Pyroglutamic acid powder is used as organic synthesis intermediates, food additives and so on.
• L-Pyroglutamic acid CAS 98-79-3 Used in food, medicine, cosmetics and other industries.

Physicochemical Property of L-Pyroglutamic acid powder

Colourless crystal. Melting point 162-163℃, soluble in water, alcohol, acetone and glacial acetic acid, slightly soluble in ethyl acetate, insoluble in ether.

Production methodprocess of L-Pyroglutamic acid powder

There are semi-synthetic method, enzyme conversion method and total synthesis method. At present, the main method of industrial production is the semi-synthetic method with glutamic acid as raw material. The 42% aqueous solution of glutamic acid is heated at 140℃ for 3h, and the reaction solution with L-Pyroglutamic acid as the main component is obtained. After concentration under reduced pressure, crystallisation, washing and drying, L-Pyroglutamic acid Raw Materials is obtained with a conversion rate of 94%.
