Product Details
Monosodium glutamate monohydrate takes the shape of white or off-white crystal granules and crystalline powder. It dissolves easily in water, slightly in ethanol and similar organic solvents, yet cannot dissolve in ether and comparable reagents. Per titration testing, its standard purity spans 98.0%–102.0%. Reputable producers Fujifilm and Heguang Pure Pharmaceutical adhere to this standard, with some of their high-end variants reaching 99% purity.

L-Glutamic acid monosodium salt monohydrate is a vital raw material and intermediate for organic, pharmaceutical and agrochemical synthesis. It also works to boost food umami taste. Besides, it can be used as a standard sample to verify how sensitive L-glutamate sensors are, and supports the preparation of alpha crystalline L-glutamic acid.
