Description

Thioformaldehyde CAS NO 865-36-1 is a highly reactive organosulfur compound, serving as the sulfur analog of formaldehyde. Its unique chemical structure makes it a valuable and versatile building block in advanced organic synthesis and materials science. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to introduce thioaldehyde or thiocarbonyl functionalities into complex molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of heterocyclic compounds, thiazoles, and other sulfur-containing active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the development of novel fungicides, herbicides, and insecticides that require specific sulfur-based molecular frameworks.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the production of specialty polymers and resins with enhanced properties.
• Organic Synthesis Reagent: Employed in cycloaddition reactions, as a dienophile in Diels-Alder reactions, and for the preparation of various thio-compounds.
• Chemical Research: Fundamental reagent in academic and industrial R&D for exploring new reaction pathways and sulfur chemistry.
• Flavor & Fragrance Industry: Potential intermediate for synthesizing certain sulfur-containing aroma chemicals, though typically in highly purified grades.

Quality Control

Our Thioformaldehyde is produced and handled under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR analysis, to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments. Our quality commitment aligns with cGMP principles where applicable for intermediate use.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and light-sensitive nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C for extended stability. Keep away from heat, sparks, and open flame.
