Description

Isopropyl Disulfide CAS NO 4253-89-8 is a specialized organosulfur compound characterized by its disulfide functional group. This chemical is valued in industrial synthesis for its role as a versatile sulfur source and building block in the production of more complex molecules. It is primarily utilized by manufacturers in the agrochemical, pharmaceutical, and specialty chemical sectors for applications requiring controlled sulfur incorporation.

Application

• As a key intermediate in the synthesis of certain agrochemicals, including pesticides and fungicides.
• Utilized in pharmaceutical research and development for creating sulfur-containing active pharmaceutical ingredients (APIs).
• Acts as a precursor or additive in the production of specialty chemicals, such as lubricant additives and rubber vulcanization agents.
• Employed in organic synthesis laboratories as a reagent for introducing the disulfide moiety into target molecules.
• Potential use in the formulation of certain flavors and fragrances where sulfur notes are desired.
• Serves as a model compound in petrochemical research for studying the behavior of sulfur-containing species.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. We employ advanced analytical techniques, including gas chromatography (GC) and nuclear magnetic resonance (NMR), to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat and ignition sources. Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent moisture ingress and oxidation.
