Description

Lenthionine (CAS NO 292-46-6) is a unique organosulfur compound recognized for its potent, characteristic aroma. This compound is of significant commercial interest as a key flavor and fragrance component, particularly in the food and flavoring industries. It is primarily sought after by manufacturers in the flavor & fragrance, food technology, and advanced organic synthesis sectors for creating authentic savory and meaty notes.

Application

• Flavor & Fragrance Industry: A critical component for imparting savory, meat-like, and alliaceous (garlic/onion) notes in processed foods, savory snacks, and culinary flavorings.
• Food Technology: Used as a flavor enhancer and modifier in meat analogs, soups, sauces, and ready-to-eat meals to boost umami and savory characteristics.
• Aroma Chemistry Research: Serves as a reference standard and a building block in the research and development of novel synthetic flavors and fragrances.
• Organic Synthesis: Acts as a specialized intermediate for synthesizing more complex sulfur-containing heterocyclic compounds for pharmaceutical and material science applications.
• Natural Product Standard: Used as an analytical standard for the identification and quantification of lenthionine in natural extracts, such as from Shiitake mushrooms (Lentinula edodes).
