L(+)-Monosodium glutamate monohydrate
High Solubility: Sodium glutamate monohydrate dissolves readily in water, making it suitable for diverse food and pharmaceutical applications.
Consistent Purity: Typically maintaining 98.0%–102.0% purity, and in some cases up to 99%, it ensures reliable quality and performance.
Premium Quality: Manufactured by reputable brands such as Fujifilm and Heguang Pure Pharmaceutical, guaranteeing safety and consistency.
Controlled Solubility: While highly soluble in water, it exhibits limited solubility in organic solvents, allowing precise use in various formulations.
Sodium glutamate monohydrate usually occurs as a white to off-white crystalline powder or crystals. It is highly soluble in water, slightly soluble in organic solvents such as ethanol, and insoluble in others like ether. High-quality products generally have a purity range of 98.0%–102.0% (titration method), with some reaching 99%, as produced by reputable manufacturers like Fujifilm and Heguang Pure Pharmaceutical.

Sodium glutamate monohydrate serves as an important raw material and intermediate in the production of pharmaceuticals, agrochemicals, and other organic compounds. It is also widely employed as a flavor enhancer in food products. In addition, it has been used as a reference compound for testing the sensitivity of L-glutamate sensors and can participate in the synthesis of the α-polymorph of L-glutamic acid.
