Sodium Pyruvate
1. Basic Product Information
Product Name: Sodium Pyruvate
CAS Number: 113-24-6
Molecular Formula: C3H3NaO3
Molecular Weight: 110.04
Synonyms: 2-Oxopropanoic acid sodium salt, Pyruvic acid sodium salt
Product Category: Biochemical culture medium raw material, cell culture additive, pharmaceutical excipient, food nutritional supplement, analytical reagent
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White to off-white crystalline powder
- Odor: Odorless
- Solubility: Freely soluble in water; slightly soluble in ethanol; insoluble in acetone, ether and organic hydrocarbon solvents
- Melting Point: Decomposes above 200 °C
- Density (20 °C): 1.45 g/cm3
- Hygroscopicity: Moderately hygroscopic under high humidity environment
- Aqueous Stability: Relatively stable in neutral and weakly acidic aqueous solutions; prone to oxidative degradation and discoloration under strong alkaline, high temperature or long-term light exposure
Chemical Characteristics
- Molecular Structure: Sodium salt of pyruvic acid containing ketone carbonyl and carboxylate functional groups
- Core Functional Mechanism: Key intermediate of cellular glycolysis pathway; provides energy for cell metabolism, reduces oxidative stress and stabilizes cell culture systems
- Photostability: Light-sensitive; prolonged UV irradiation accelerates oxidation to form dark impurities
- Thermal Stability: Stable below 150 °C; high-temperature decomposition releases irritating volatile organic acid fumes
- Chemical Compatibility: Compatible with common cell culture buffers and inorganic salts; incompatible with strong oxidants, concentrated strong alkalis and heavy metal ions
3. Main Application Fields
- Core Application: Cell & Tissue Culture Reagent
Essential energy supplement for mammalian cell culture medium; improves cell viability, alleviates oxidative damage and supports long-term cell passage - Biochemical & Molecular Biology Research
Substrate for enzyme activity assays, mitochondrial function tests and metabolic pathway research - Pharmaceutical Excipient & Raw Material
Stabilizer for injection formulations, auxiliary material for liver-protective and anti-oxidant oral preparations - Functional Food & Health Product Additive
Nutritional anti-oxidant additive applied in weight management and anti-fatigue health food - Clinical Diagnostic Reagent
Component of biochemical detection kits for blood metabolism index testing
4. Platform Category & Product Group Guidance
