Description

Methyl Propyl Disulfide is a sulfur-containing organic compound characterized by its distinct organoleptic properties. This chemical is significant for its role as a flavor and fragrance ingredient, imparting savory, alliaceous, or meaty notes to various formulations. It is primarily needed by manufacturers in the flavor and fragrance, food processing, and agrochemical industries for creating authentic sensory profiles and developing specialized intermediates.

Application

• Flavor & Fragrance Industry: Used as a key aroma chemical to replicate the savory, onion, garlic, or cooked meat notes in savory flavors, seasonings, and reaction flavors.
• Food Processing: Employed as a processing aid or flavor enhancer in meat analogs, snack foods, soups, sauces, and ready-to-eat meals.
• Agrochemical Intermediates: Serves as a valuable building block in the synthesis of certain pesticides, herbicides, or plant growth regulators.
• Organic Synthesis: Acts as a reagent or intermediate in pharmaceutical research and the production of specialty chemicals, leveraging its disulfide functional group.
• Research & Development: Utilized in analytical laboratories as a reference standard for gas chromatography (GC) or mass spectrometry (MS) in food and environmental analysis.

Quality Control

Our Methyl Propyl Disulfide is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency, meeting the requirements for flavor and fragrance applications. A Certificate of Analysis (COA) detailing specifications such as assay, refractive index, and specific gravity is provided with every shipment to guarantee traceability and compliance.

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 headspace in partially used containers. Recommended storage temperature: 2-8°C (refrigerated) for optimal shelf life.
