Description

Allyl Isothiocyanate is a naturally occurring organosulfur compound responsible for the pungent, sharp flavor and aroma characteristic of mustard, horseradish, and wasabi. This highly volatile, clear to pale yellow liquid is a key bioactive component and flavoring agent. It is in high demand across the food, flavor & fragrance, and agricultural industries for its unique sensory properties and biocidal activity. Global B2B buyers rely on consistent, high-purity supplies to ensure product quality and regulatory compliance.

Application

• Food & Flavor Industry: Primary use as a pungent flavoring agent in mustards, sauces, dressings, and savory snacks.
• Fragrance & Aromatherapy: Used in trace amounts to create sharp, spicy top notes in perfumery compositions.
• Agricultural & Pest Control: Acts as a natural biofumigant and soil treatment agent due to its pesticidal and nematicidal properties.
• Pharmaceutical & Nutraceutical Research: Investigated for its potential bioactive effects, including antimicrobial and anti-inflammatory properties.
• Chemical Synthesis: Serves as a versatile building block (allylating agent) in organic synthesis for pharmaceuticals and agrochemicals.
• Analytical Chemistry: Used as a standard or reagent in chromatography and other analytical methods.

Quality Control

Our Allyl Isothiocyanate is produced and tested under a strict quality management system to ensure batch-to-batch consistency and purity. We offer grades suitable for food flavoring (FCC) and industrial applications, with specifications tailored to meet your requirements. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee compliance with your specifications and relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, containers should be kept tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
