1. Basic Info
Name: Methyl salicylate
Alias: Wintergreen oil, Methyl 2-hydroxybenzoate
CAS No.: 119-36-8
Molecular Formula: C8H8O3
Molecular Weight: 152.15
2. Physical & Chemical Properties
Physical Properties
- Appearance: Colorless to pale yellow transparent oily liquid
- Odor: Strong characteristic wintergreen mint aroma
- Solubility: Slightly soluble in water; miscible with ethanol, methanol, ether, chloroform, acetone, vegetable oils
- Density (20℃): 1.180–1.188 g/cm3
- Boiling Point: 220–224 ℃
- Melting Point: -8.6 ℃
- Refractive Index nD2?: 1.534–1.538
- Closed-cup Flash Point: 101 ℃
- Vapor pressure: Low volatility at room temperature, obvious fragrance diffusivity
- Hygroscopy: Non-hygroscopic
Chemical Properties
- Molecular structure: Contains phenolic hydroxyl group and methyl ester group of benzoic acid
- Hydrolysis reaction: Under alkaline heating conditions, hydrolyzes to salicylic acid and methanol
- Esterification & transesterification: Reacts with alcohols to generate other salicylate esters under acid catalysis
- Phenolic hydroxyl activity: Weak acidity, can form stable salts with sodium hydroxide, potassium hydroxide
- Thermal stability: Stable below 180℃; long-term high-temperature heating causes slight discoloration and ester decomposition
- Photostability: Avoid long-term strong light irradiation; UV light will make liquid turn yellow and produce impurities
- Anti-inflammatory pharmacodynamic characteristic: In vivo hydrolyzed to salicylic acid, inhibits prostaglandin synthesis
- Compatibility: Compatible with most flavor solvents, cosmetic oils, ointment substrates; incompatible with strong alkaline substances, heavy metal salts, strong oxidants
