Nicotinic Acid
1. Basic Product Information
Product Name: Nicotinic Acid
CAS Number: 59-67-6
Molecular Formula: C6H5NO2
Molecular Weight: 123.11
Synonyms: Niacin, 3-Pyridinecarboxylic acid, Vitamin B3
Product Category: Biochemical raw material, food & feed nutritional fortifier, pharmaceutical excipient, cosmetic additive, analytical reagent
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White crystalline powder or colorless crystal
- Odor: Odorless, faint sour taste
- Solubility: Sparingly soluble in cold water, freely soluble in hot water; soluble in ethanol, methanol; insoluble in ether, benzene and aliphatic hydrocarbons
- Melting Point: 234–238 °C (sublimes simultaneously)
- Density (20 °C): 1.47 g/cm3
- Hygroscopicity: Non-hygroscopic under sealed dry storage
- Aqueous Stability: Stable in neutral, weakly acidic and weakly alkaline aqueous solutions; no obvious hydrolysis under room temperature conditions
Chemical Characteristics
- Molecular Structure: Pyridine heterocycle with carboxyl group at the 3-position, amphoteric heterocyclic carboxylic acid
- Core Functional Mechanism: Essential water-soluble vitamin; participates in human lipid metabolism, energy generation and cellular respiration; forms nicotinamide coenzymes in vivo
- Photostability: Stable under normal sealed dry storage; slight discoloration upon long-term intense UV radiation
- Thermal Stability: Stable below 200 °C; sublimates significantly above melting point; high-temperature decomposition releases irritating nitrogen-containing fumes
- Chemical Compatibility: Compatible with most inorganic salts, cosmetic raw materials and food substrates; incompatible with strong oxidants and concentrated strong bases
3. Main Application Fields
- Core Application: Food & Feed Nutritional Supplement
Vitamin fortifier added to flour, beverages, dairy products and animal feed to prevent pellagra and improve animal growth performance - Pharmaceutical Raw Material & Excipient
Active ingredient for lipid-lowering oral preparations; pH regulator and stabilizer for injections, oral tablets and compound vitamin formulations - Cosmetic Functional Raw Material
Anti-aging, brightening and oil-controlling additive for facial creams, essences and body care products - Biochemical & Laboratory Reagent
Substrate for enzyme activity assays, cell culture medium additive and standard reference for vitamin detection kits - Industrial Synthetic Intermediate
Building block for synthesizing pyridine-based agrochemicals and pharmaceutical derivatives
4. Platform Category & Product Group Guidance
