Applications
1. Food & Beverage Industry
- Used as a flavor enhancer and sweetener in beverages, confectionery, and seasonings.
- Functions as a buffering agent to stabilize taste and control acidity.
- Applied in nutrition drinks and functional foods as a source of amino acids.
2. Pharmaceutical & Nutraceuticals
- Raw material for amino acid injections, infusion solutions, and compound amino acid preparations.
- Used in tablets, capsules, and dietary supplements for sports nutrition, sleep support, and general health formulations.
- Serves as an intermediate in the synthesis of certain APIs and excipients.
3. Animal Feed & Pet Nutrition
- Added to feed premixes to improve palatability and provide additional amino acid nutrition.
- Applied in pet food formulations to enhance flavor and support protein balance.
4. Agrochemicals & Industrial Use
- Intermediate in the production of some herbicides and plant protection products.
- Used as a complexing agent and buffering agent in electroplating, metal treatment, and other industrial processes.
- Employed as a stabilizer in various formulations where mild buffering is required.
If you need a specific application grade (e.g., herbicide intermediate, injection grade, or feed grade), we can adjust specifications and documentation accordingly.
Storage Conditions
- Store in a cool, dry, and well-ventilated warehouse.
- Keep away from moisture, direct sunlight, and high temperature.

- Recommended storage temperature: ≤ 30°C.
- Under proper storage conditions, typical shelf life is 24 months from production date.
Safety Precautions
Although glycine is considered low in toxicity and widely used in food and pharmaceutical products, it should still be handled following standard industrial hygiene practices:
- Avoid excessive dust generation; use local exhaust ventilation where dust may form.
- Wear appropriate PPE during handling: dust mask or respirator, safety goggles, and gloves.
- Prevent contact with eyes. In case of eye contact, rinse immediately with plenty of water and seek medical advice if irritation persists.
- If swallowed in industrial quantities, rinse mouth and drink water; seek medical attention if any discomfort occurs.
- Keep out of reach of children and untrained personnel.
- Follow local regulations for handling, transport, and disposal of chemical substances.

FAQ - Technical & Supply Chain
-
Q:
What unique chemical characteristic distinguishes Glycine (CAS 56-40-6) from all other proteinogenic amino acids?
A: Glycine is the only proteinogenic amino acid that is achiral, meaning it does not have a D- or L- isomer optical rotation because its side chain consists simply of a single hydrogen atom; this structural simplicity provides it with exceptional conformational flexibility in protein chains. -
Q:
Is this powder grade intended for use as a buffering agent in chemical synthesis?
A: Yes, due to its amphoteric nature (containing both acidic and basic groups), Glycine is extensively intended for use as a buffering agent to maintain stable pH levels in biochemical research, pharmaceutical preparations, and industrial chemical reactions.
