What is Sodium Pyruvate CAS 113-24-6?

Sodium Pyruvate is the sodium salt of pyruvic acid, with the molecular formula C3H3NaO3 and CAS number 113-24-6. It is normally a white to slightly yellow crystalline powder with high water solubility and is used as a pyruvate source in bioprocessing, fermentation and nutrition-related formulations.

Why is Sodium Pyruvate added to cell culture media?

In cell culture, sodium pyruvate serves as an auxiliary energy source and metabolic intermediate. It can enter central carbon metabolism to support cellular respiration and may help reduce hydrogen peroxide accumulation, so it is often included in media for sensitive or high-energy-demand cells.

What is the difference between Sodium Pyruvate and pyruvic acid?

Pyruvic acid is the free acid form, while sodium pyruvate is its more stable, water-soluble sodium salt. The salt form is easier to handle and formulate into aqueous media, and it avoids the stronger acidity and handling concerns associated with the free acid.

What are the main application areas of Sodium Pyruvate?

Sodium Pyruvate is used as a cell-culture supplement, as a substrate in fermentation, and as a pyruvate ingredient in selected food, beverage and nutrition products where permitted. Industrial and food grades allow buyers to choose a purity and testing profile suitable for the intended process.

How should Sodium Pyruvate be stored?

Sodium Pyruvate should be kept tightly closed in a cool, dry, well-ventilated area and protected from moisture and direct sunlight. Since it is water-soluble and can absorb moisture, containers should be resealed after use and storage conditions should follow the supplier's label guidance for the selected grade.

Sodium Pyruvate CAS 113-24-6

Sodium Pyruvate CAS 113-24-6 is the stable sodium salt of pyruvic acid, chemically identified as Sodium 2-oxopropanoate, serving as a critical metabolic intermediate in bioprocessing and organic synthesis. Also known as Pyruvic acid sodium salt or Sodium alpha-ketopropionate, it is utilized to enhance cellular energy metabolism in industrial cell culture media and functions as a buffering reactant in fine chemical manufacturing.

If you tell me your target market (EU/US/Middle East), I can align the “grade wording” more strictly to local compliance language.

Storage Conditions

Store in cool, dry, well-ventilated warehouse; keep containers tightly sealed.
Protect from moisture (hygroscopic materials may cake).
Recommended storage: 0–10 °C refrigerated for best stability is commonly suggested by suppliers; avoid heat.
Keep away from contamination and strong oxidizers.

Safety Precautions

Avoid dust generation and inhalation; use local ventilation and a dust mask/respirator when needed.
Wear protective gloves and safety goggles; wash hands after handling.
First aid (general): rinse eyes with water for several minutes; wash skin with soap and water; move to fresh air if inhaled.
SDS can be provided upon request.
