Description

Allyl Propyl Disulfide is an organosulfur compound characterized by its distinct, potent aroma. This chemical is valued for its role as a key flavor and fragrance component, replicating the characteristic notes of garlic and onion. It is primarily sought after by manufacturers in the food flavoring, fragrance, and agricultural chemical industries for creating authentic savory profiles and developing specialized intermediates.

Application

• Flavor & Fragrance Industry: A crucial building block for synthesizing authentic garlic and onion flavorings used in processed foods, seasonings, sauces, and savory snacks.
• Aroma Chemicals: Serves as a key ingredient in fine fragrances, personal care products, and household cleaners to impart sharp, pungent, or savory olfactory notes.
• Agrochemical Intermediates: Used in the research and synthesis of specialized pesticides, herbicides, or plant growth regulators due to its bioactive disulfide structure.
• Organic Synthesis: Acts as a versatile reagent or intermediate in organic chemistry for constructing more complex sulfur-containing molecules in pharmaceutical and chemical research.
• Food Science Research: Employed in analytical laboratories as a reference standard for quality control and authenticity testing of garlic and onion-derived products.

Quality Control

Our Allyl Propyl Disulfide is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets stringent purity and identity specifications, with testing typically including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your requirements.

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 and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize degradation. Recommended storage temperature is 2-8°C.
