Applications of Allyl Isothiocyanate

Food & Flavour Industry

Allyl Isothiocyanate is used in condiments, pickled vegetables, sauces and snacks to impart a sharp, mustard-like kick and enhance sensory appeal. It also has antimicrobial and preservative properties, helping extend the shelf life of packaged foods.

Agricultural & Crop Protection

Due to its antimicrobial, fumigant, and nematicide activity, Allyl Isothiocyanate is used in soil treatments and crop protection systems.

Chemical & Research Use

Used as a reactive intermediate in chemical synthesis, particularly where isothiocyanate functionality is required. Also used in research exploring its potential health benefits (anticancer, detox enzyme activation).

Safety & Handling Guidelines

Storage: Store in a well-sealed container in a cool, dry, ventilated space away from heat, sparks and strong oxidisers.
Safety: Highly pungent, irritating to eyes, skin and respiratory system; flammable oily liquid.
Precaution: Use with appropriate PPE (gloves, goggles, fume hood) and avoid prolonged exposure. Check MSDS for full hazard profile.
