Applications
DUDLEY’s Methyl thioacetate (CAS: 16630-66-3) is used in both the fine chemical and fragrance industries.
1. Pharmaceutical and Pesticide Intermediates:
Heterocyclic Synthesis: Utilizing the active methylene and ester groups in their molecules, Claisen condensation or cyclization reactions can be performed to synthesize sulfur-containing heterocyclic derivatives such as thiophenes and thiazoles. These structures are widely found in antibacterial and anti-inflammatory drugs.
Functional Group Conversion: They can serve as donors for methyl thio (-SMe) groups or be used to prepare corresponding sulfoxide/sulfone intermediates through oxidation.
2. Flavors & Fragrances:
Edible Flavors: Used at very low concentrations to formulate edible flavors with tropical fruit (such as pineapple, durian) or specific vegetable (such as potato, onion) flavors.
Chemical Flavors: Used to formulate certain chemical fragrance bases with special styles.
