Description

1,2,4-Trithiolane CAS NO 289-16-7 is a unique organosulfur compound characterized by a five-membered ring containing three sulfur atoms. This structure is of significant interest in flavor and fragrance chemistry, as it is a key contributor to the characteristic aroma of cooked foods like meat and garlic. It serves as a critical intermediate and reference standard for research and development in the flavor, fragrance, and food science industries. Professionals in these fields rely on high-purity 1,2,4-Trithiolane to replicate authentic savory notes and study sulfur-based aroma chemistry.

Application

• Flavor & Fragrance (F&F) Industry: A key aroma compound used to impart savory, meaty, roasted, and garlic-like notes in savory flavor formulations.
• Food Science Research: Employed as a reference standard to study and quantify the Maillard reaction products responsible for cooked food aromas.
• Synthetic Chemistry: Valuable as a building block or intermediate in the synthesis of more complex sulfur-containing heterocyclic compounds.
• Analytical Standards: Used for calibration and method development in gas chromatography (GC) and mass spectrometry (MS) for food and flavor analysis.
• Seasoning & Processed Foods: Incorporated into flavor systems for snacks, soups, sauces, and ready-to-eat meals to enhance umami and savory profiles.
