In the intricate world of agrochemicals, specific chemical compounds serve as the foundational elements for powerful crop protection products. Ethyl 3-Chlorosulfonyl-1-Methylpyrazole-4-Carboxylate, identified by its CAS number 93621-38-6, is one such indispensable intermediate. Its primary role in the synthesis of Pyrazosulfuron-Ethyl, a widely used herbicide, makes it a compound of significant interest to R&D scientists, procurement managers, and formulators in the agricultural industry. This article highlights the significance of CAS 93621-38-6 and guides potential buyers on sourcing this crucial material.

The Significance of CAS 93621-38-6 in Agrochemical Synthesis

CAS 93621-38-6, also known as Ethyl 3-chlorosulfonyl-1-methylpyrazole-4-carboxylate, is a white solid chemical that acts as a vital precursor in the production of Pyrazosulfuron-Ethyl. Pyrazosulfuron-Ethyl is renowned for its effectiveness in controlling various weeds that plague rice paddies and other agricultural lands. The efficacy of the final herbicide is directly dependent on the purity and quality of its intermediates. Therefore, manufacturers and formulators prioritize sourcing this compound from suppliers who can guarantee high standards, such as an assay of ≥99.0% and a low loss on drying (≤0.5%). The consistent molecular structure and minimal impurities ensure that the subsequent chemical reactions proceed as intended, leading to a high-quality, active herbicide ingredient. For businesses looking to buy, understanding these critical specifications is the first step.

Sourcing Strategies for CAS 93621-38-6
