Description

L-(+)-Glutamic Acid Hydrochloride is the hydrochloride salt of the naturally occurring L-isomer of glutamic acid, a key amino acid. This high-purity derivative is essential for applications requiring precise chirality and enhanced solubility in aqueous systems. It serves as a critical building block and reagent in the pharmaceutical, biotechnology, and food ingredient sectors, where consistent quality and reliable supply are paramount.

Application

• Pharmaceutical Synthesis: As a chiral intermediate in the production of peptides, active pharmaceutical ingredients (APIs), and other bioactive compounds.
• Biochemical Research: Used in cell culture media, as a nutrient component, and in enzymatic studies requiring specific amino acid substrates.
• Food & Flavor Industry: Acts as a precursor for flavor enhancers like monosodium glutamate (MSG) and other umami-related compounds.
• Nutraceuticals & Supplements: Incorporated into formulations for specialized amino acid supplements and infusion solutions.
• Cosmetic Applications: Utilized in the formulation of hair and skin care products for its moisturizing and conditioning properties.
• Chemical Synthesis: Serves as a protected form of glutamic acid for organic synthesis and polymer chemistry.

Quality Control

Our L-(+)-Glutamic Acid Hydrochloride is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, chiral purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
