1. Basic Information
Name: Succinic acid
Alias: Butanedioic acid
CAS No.: 110-15-6
Molecular Formula: C4H6O4
Letter-number format molecular formula: C4H6O4
Molecular Weight: 118.09
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline granule or fine powder
- Odor: Odorless, slight characteristic sour taste
- Solubility: Soluble in hot water, moderately soluble in cold water; soluble in ethanol, methanol, acetone; slightly soluble in ether; insoluble in benzene, alkane solvents
- Melting Point: 185–187 °C
- Hygroscopicity: Non-hygroscopic under normal ambient humidity
- Crystal characteristic: Monoclinic crystal, easy to recrystallize from water
Chemical Properties
- Molecular Structure: Linear saturated dicarboxylic acid with two terminal carboxyl groups
- Acid-base reaction: Weak organic dibasic acid, neutralizes alkalis to generate succinate salts
- Esterification & cyclization: Under heating dehydration to form succinic anhydride; reacts with alcohols to produce succinate esters
- Polymerization property: Copolymerizes with diols to synthesize biodegradable PBS plastic
- Thermal stability: Stable below 150 °C; dehydrates into succinic anhydride above melting point
- Photostability: Stable under indoor light, no light-induced degradation
- Compatibility: Compatible with most food, cosmetic and pharmaceutical raw materials; incompatible with strong oxidants, strong alkali at high temperature
3. Main Application Fields

Safety Warning
Low-toxicity edible organic acid. Dust irritates eyes and respiratory tract; concentrated aqueous solution causes mild skin irritation. Wear dust mask and protective gloves during operation. Avoid long-term high-temperature storage to prevent dehydration into anhydride. Waste liquid can be neutralized and discharged normally; solid residue belongs to general organic waste.
