L-Glutamic Acid Hydrochloride (CAS 138-15-8) is the monohydrochloride salt of L-glutamic acid (C5H10ClNO4). As a water-soluble, acidic glutamic-acid source it is used as a food acidulant and seasoning ingredient, as a nutritional supplement, and as a raw material in synthesis.

Frequently Asked Questions

What is L-Glutamic Acid Hydrochloride used for?

It is the monohydrochloride salt of L-glutamic acid (CAS 138-15-8, C5H10ClNO4). As a water-soluble, acidic glutamate source it is used as a food acidulant and seasoning ingredient, as a nutritional amino-acid input, and as a raw material in downstream synthesis.

How does it differ from L-glutamic acid base?

This is the hydrochloride salt rather than the free acid. The salt form provides higher water solubility and stronger acidulant behavior, which is why it is chosen where a soluble, acidic glutamate source is needed.

Is L-Glutamic Acid Hydrochloride water soluble?

Yes. The hydrochloride salt is the water-soluble form of L-glutamic acid, making it well suited to aqueous seasoning and acidulant applications.

What is the CAS number, formula, and HS code?

CAS 138-15-8, formula C5H10ClNO4, HS 2922.42 (glutamic acid and its salts). Supplied to FCC specification; lot-specific CoA and SDS are available on request.

What bulk packaging and order quantities are available?

It is distributed as an FCC food-grade ingredient in bulk packaging for manufacturing use. Submit your target volume and documentation requirements through a bulk RFQ for current pricing, pack sizes, and lead time.
