Physical & Chemical Properties
Physical Properties
- Appearance: Colorless to pale yellow clear viscous liquid
- Odor: Strong meaty, roasted, nutty characteristic odor
- Melting Point: <25 °C
- Boiling Point: 135 °C (7 mmHg, lit.)
- Density: 1.196 g/mL at 25 °C (lit.)
- Refractive Index: n??/D 1.550 (lit.)
- Flash Point: >230 °F (109.7 °C)
- Solubility: Very soluble in water; soluble in alcohol, benzene, chloroform and ether
- Vapor Pressure: 0.0±0.6 mmHg at 25 °C
Chemical Properties
- Chemical Stability: Stable in sealed, cool and dry environment at room temperature; sensitive to strong acids and strong bases.
- Acid-Base Character: Weakly acidic due to the hydroxyl group; forms salts with strong bases.
- Reactivity: Undergoes typical reactions of hydroxyl groups (esterification, etherification) and thiazole ring (substitution, oxidation).
- Thermal Stability: Decomposes at high temperature (>200 °C) to release toxic sulfur-containing gases.
- Hygroscopicity: Slightly hygroscopic; keep tightly sealed to prevent moisture absorption.
- Incompatibility: Incompatible with strong oxidants, strong acids and alkaline metals; avoid mixed storage.
Applications
- Food & Beverage Industry: Key flavor enhancer for savory products, used in meat products, soups, sauces, snacks, dairy products, baked goods and beverages to boost meaty and roasted notes.
- Pharmaceutical Industry: Intermediate for synthesizing thiamine (vitamin B1) and other sulfur-containing drugs; used in pharmaceutical formulation as a solubilizer.
- Cosmetics & Fragrances: Applied in daily fragrances and cosmetic additives to provide unique meaty or nutty aroma.
- Biochemical Research: Standard reagent for heterocyclic chemistry research; used in the synthesis of N-heterocyclic carbene (NHC) catalysts.
- Fine Chemicals: Critical intermediate for manufacturing thiazole derivatives, surfactants and agricultural chemicals.
Usage Restriction: For food flavoring, pharmaceutical synthesis and scientific research use only. Strictly prohibited for illegal processing and improper application.
Storage & Transportation Instructions
