SHORT DESCRIPTION

Ammonium Lactate Extra Pure is a high-purity, white to off-white crystalline or powdery compound formed from lactic acid and ammonium hydroxide, commonly used in laboratory settings for biochemical, pharmaceutical, and analytical applications. It serves as a buffering agent, a mild acidifier, and a source of both lactate and ammonium ions in solution. In biochemical research, it is used in studies involving metabolic pathways, pH-controlled reactions, and cell culture media. Its extra pure grade ensures minimal contamination, making it suitable for sensitive analytical techniques and formulation development. To maintain stability and prevent moisture absorption, it should be stored in tightly sealed containers in a cool, dry environment.

Description

USES

Primary Uses

Buffering Agent in Biochemistry and Cell Culture
- Used as a mild buffer for maintaining near-neutral pH in sensitive biological experiments, especially in low-ionic strength environments.
Source of Lactate Ions in Metabolic Studies
- Provides lactic acid conjugate base in experiments modeling anaerobic metabolism and cellular respiration.
Nutrient Additive in Microbial Culture Media
- Acts as a carbon source for certain bacteria or fungi in microbiology and fermentation experiments.
Reagent in Food Chemistry and Cosmetic Science Research
- Studied in lab-scale modeling of preservative behavior, pH adjustment, and skin compatibility tests.
Chelating Agent in Inorganic Studies
- The lactate ion can act as a mild chelator, useful in solubilizing metal ions like calcium, magnesium, or iron.

Secondary Uses

Simulation of Biological Fluids or Fermentation Byproducts
- Used in modeling sweat, wound fluid, or spoilage products in lab-based degradation or stability studies.
Redox and Acid–Base Studies in Educational Labs
- Demonstrates weak acid–weak base salt behavior, suitable for titration or hydrolysis experiments.
Solubilizer in Experimental Drug Delivery Systems
- Investigated as a vehicle for solubilizing APIs or test compounds in pharmacokinetic simulations.
pH Adjustment in Gel or Polymer Systems
- Occasionally used in forming hydrogels or buffers for controlled-release materials in laboratory tests.
Precursor for Organically Modified Lactate Complexes
- Used in the synthesis of metal lactate salts (e.g., iron or zinc lactates) in coordination and nutritional chemistry studies.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):
- Wear a lab coat, safety goggles, and chemical-resistant gloves (e.g., nitrile).
- Use in a well-ventilated area or under a fume hood to prevent inhalation of vapors or mists.
Handling:
- Avoid contact with eyes, skin, and clothing.
- Prevent inhalation of vapors or aerosols.
- Avoid mixing with strong oxidizing agents or strong acids/bases.
Storage:
- Store in a tightly sealed container in a cool, dry, and well-ventilated area.
- Protect from heat, light, and moisture.
- Keep away from incompatible substances such as strong oxidizers.
Hygiene Measures:
- Wash hands thoroughly after handling.
- Do not eat, drink, or smoke while handling chemicals.
- Keep the working area clean and dry.

FIRST AID MEASURES

Inhalation:
- Move the person to fresh air.
- If breathing becomes difficult, administer oxygen.
- Seek medical attention if symptoms like coughing or irritation persist.
Skin Contact:
- Remove contaminated clothing.
- Rinse skin thoroughly with soap and water.
- Seek medical advice if irritation occurs.
Eye Contact:
- Rinse cautiously with water for at least 15 minutes.
- Remove contact lenses if present and easy to do.
- Seek medical attention if irritation persists.
Ingestion:
- Rinse mouth with water.
- Do not induce vomiting.
- If the person is conscious, give water to dilute.
- Seek immediate medical attention—ingestion may cause irritation to the digestive tract.

FIRE FIGHTING MEASURES

Suitable Extinguishing Media:
- Use dry chemical, carbon dioxide (CO₂), alcohol-resistant foam, or water spray, depending on surrounding materials.
