Description

Thioacrolein is a highly reactive sulfur-containing organic compound, specifically an α,β-unsaturated thioaldehyde. This unique chemical structure makes it a valuable and versatile building block in advanced organic synthesis. It is primarily utilized by research and development chemists in the pharmaceutical and agrochemical industries for constructing complex heterocyclic frameworks and sulfur-functionalized molecules. Thioacrolein CAS NO 53439-64-8 is a critical intermediate for developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of sulfur-containing heterocycles, such as thiophenes and thiazoles, which are core structures in many active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides that incorporate sulfur for enhanced biological activity.
• Material Science Research: Serves as a precursor for developing specialized polymers and organic electronic materials with unique conductive or optoelectronic properties.
• Chemical Research & Development: An essential reagent in academic and industrial R&D labs for exploring new organic reactions, particularly [4+2] cycloadditions and nucleophilic additions.
• Flavor & Fragrance Chemistry: Intermediate for synthesizing sulfur-based compounds that contribute to savory, roasted, or meaty notes in complex aroma profiles.

Quality Control

Our Thioacrolein is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity for research and synthesis applications. We employ advanced analytical techniques, including GC, GC-MS, and NMR, for comprehensive characterization and purity verification. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its reactive and easily oxidized nature, minimize exposure to air and moisture. Keep away from heat, sparks, and open flame.
