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.
- Store in tightly closed original packaging to avoid caking and contamination.
- Keep away from strong oxidizing agents and strong acids.
- 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 is Glycine CAS 56-40-6?
A: Glycine is the simplest proteinogenic amino acid and is supplied as a white crystalline powder. Unlike most amino acids it is achiral, which makes it especially useful in pH-buffering, synthesis and formulation applications. -
Q:
Which grades and packaging are available?
A: This product is available in industrial, food and pharmaceutical grades. It is normally packed in 25 kg kraft paper bags with an inner PE liner, with 500-1000 kg jumbo bags available on request. -
Q:
What are the main applications of glycine?
A: Glycine is used in food and beverage formulations, pharmaceutical excipients and amino-acid infusions, animal nutrition, personal-care products, metal complexing and electroplating, and as a synthesis intermediate. -
Q:
Why is glycine used as a buffering agent?
A: Because glycine has both a carboxyl and an amino group, it can buffer at both acidic and basic pH ranges. This amphoteric behavior helps maintain stable pH in chemical, biochemical and pharmaceutical processes. -
Q:
How should glycine be stored and handled?
A: Keep it in tightly closed containers in a cool, dry, ventilated area away from moisture, strong oxidizers and incompatible materials. Use local exhaust or dust-control measures and appropriate PPE when handling large quantities. -
Q:
What specifications should I confirm before ordering?
A: Confirm grade, assay, appearance, pH, loss on drying, residue on ignition, chloride, sulfate, heavy metals and any microbial limits relevant to the end use. Request the current batch analysis, technical data and safety information for batch-specific data.
