Description

4-Thiazolecarbonyl Chloride, 2-Methyl- (9Ci) is a versatile and highly reactive organic intermediate, specifically an acyl chloride derivative of a methyl-substituted thiazole. This compound is valued for its role as a key building block in the synthesis of more complex heterocyclic molecules, enabling the introduction of the 2-methyl-4-thiazolecarbonyl moiety. It is primarily sought by research and development chemists in the pharmaceutical and agrochemical industries for creating novel active ingredients, as well as by fine chemical manufacturers producing specialty compounds.

Application

• Pharmaceutical Intermediate: A critical building block for the synthesis of potential drug candidates, particularly in medicinal chemistry programs targeting new therapeutic agents.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides, herbicides, and fungicides where the thiazole ring system is a key pharmacophore.
• Material Science Research: Employed in the development of novel organic materials, including ligands for catalysis or components for advanced polymers.
• Chemical Biology & Proteomics: Can serve as a reagent for modifying proteins or other biomolecules to study biological function or create biochemical probes.
• Fine Chemical Production: Integral in custom synthesis and contract manufacturing for producing specialty chemicals with specific functionalization.

Quality Control

Every batch of 4-Thiazolecarbonyl Chloride, 2-Methyl- (9Ci) is produced and tested under strict quality management protocols to ensure consistency and reliability for your synthetic processes. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, providing full transparency on purity and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
