Furfuryl Mercaptan CAS 98-02-2

1. Acts Furfuryl mercaptan CAS 98-02-2 as a FEMA-approved flavor additive to endow roasted coffee, cocoa, nuts and meat products with rich burnt, smoky and savory notes.

2. Serves Furfuryl mercaptan as a key intermediate for synthesizing sulfur-containing pharmaceuticals, agrochemicals and flavor compounds via thiol substitution and oxidation reactions.

3. Functions as a standard reference material for detecting volatile sulfur aromas in food quality testing and coffee flavor profile analysis.

Store furfuryl mercaptan (CAS 98-02-2, colorless to pale yellow liquid, FEMA 2493, flash point 45°C, flammable, air-sensitive) in sealed amber glass containers under nitrogen at 2–8°C in a cool, dark, explosion-proof, well-ventilated area. Isolate from strong oxidants, acids and heavy metals to prevent oxidation and odor deterioration. Wear nitrile gloves, safety goggles and a half-face respirator; avoid inhalation, skin/eye contact and ingestion to prevent irritation and acute toxicity. Reseal tightly post-use; dispose of waste per local hazardous chemical and food additive rules.

Furfuryl mercaptan CAS 98-02-2 is a food flavor additive, chemical intermediate and research reagent, not for direct human ingestion in pure form; undiluted intake may cause severe gastrointestinal, respiratory and skin/eye irritation, even acute toxicity.

In regulated applications, Furfuryl mercaptan enhances the authentic roasted aroma of food, supports the synthesis of high-value sulfur-containing fine chemicals, and enables accurate identification of key flavor substances in food research.
