China 2-Chloro-5-chloromethylthiazole CCMT Suppliers | Factory Direct High-Purity Insecticide Intermediate CAS:105827-91-6
🧪
2-Chloro-5-chloromethylthiazole (CCMT) is a pale yellow crystalline or pale yellow liquid with a content of ≥98% and a melting point of 29-31℃. It serves as an essential intermediate for the synthesis of second-generation neonicotinoid insecticides.
CCMT is critical for producing advanced insecticides such as thiamethoxam, thiamethionam, and chlorothalonil. While the mechanism of action of these second-generation neonicotinoid insecticides is similar to their predecessors, they offer significant improvements including lower dosage requirements, a broader spectrum of action, and enhanced safety profiles.

Versatile Pest Control: These insecticides can effectively control both above-ground and underground pests. They are suitable for treating stems, leaves, soil, and seeds.
⚙️
Configuration Method: Using 3-chloropropene as the raw material, chlorine gas (or compounds that can generate chlorine gas, such as sulfonyl chloride) and the chloroform solution of 1-isothiocyanato-2-propene are simultaneously injected into the refluxing chloroform solution for reaction.
What are the physical properties of 2-Chloro-5-chloromethylthiazole?
CCMT appears as a pale yellow crystalline or liquid substance with a purity of at least 98% and a melting point between 29-31℃.
Which insecticides are synthesized using CCMT?
It is a key intermediate for second-generation neonicotinoids, including thiamethoxam, thiamethionam, and chlorothalonil.
What are the advantages of second-generation neonicotinoids?
They offer lower dosage requirements, a broader spectrum of pest control, and higher safety compared to the first generation.
How is CCMT applied in agriculture?
It can be used to treat various parts of the plant and environment, including stems, leaves, soil, and seeds to control both surface and underground pests.
What is the basic synthesis process for CCMT?
It is produced by reacting 3-chloropropene with chlorine gas (or sulfonyl chloride) and 1-isothiocyanato-2-propene within a refluxing chloroform solution.
What is the purity standard for industrial CCMT?
High-quality CCMT typically maintains a content level of ≥98% for effective chemical synthesis.
