Understanding the fundamental chemistry of agrochemical intermediates is vital for researchers, formulators, and procurement specialists. Pyraclostrobin (CAS 175013-18-0), a cornerstone fungicide, possesses a unique molecular structure and synthesis pathway that contributes to its broad-spectrum efficacy. This article explores the chemical intricacies of Pyraclostrobin and its significance in modern agriculture.

Molecular Structure and Properties

Pyraclostrobin's chemical name is methyl N-[2-[[1-(4-chlorophenyl)-1H-pyrazol-3-yl]oxymethyl]phenyl]-N-methoxycarbamate. Its molecular formula is C19H18ClN3O4, with a molecular weight of approximately 387.82 g/mol. The structure features a chlorophenyl pyrazole moiety linked via an oxymethyl bridge to a phenyl methoxycarbamate group. This complex arrangement is responsible for its ability to bind to the Qo site of the cytochrome bc1 complex in fungi, effectively blocking electron transport and inhibiting respiration.

The physical appearance of high-purity Pyraclostrobin is typically a white to off-white powder. Its properties, such as solubility and stability, are carefully managed during manufacturing to ensure optimal performance in formulations. For those looking to buy Pyraclostrobin, understanding these properties is key to effective application.

Synthesis Pathways for Pyraclostrobin

The synthesis of Pyraclostrobin involves multi-step chemical reactions, often starting from simpler aromatic and heterocyclic precursors. A common approach involves the coupling of a substituted pyrazole derivative with a suitably functionalized phenyl intermediate, followed by esterification and carbamate formation. The precise synthesis route employed by a Pyraclostrobin manufacturer can influence purity levels, cost-effectiveness, and the environmental footprint of the production process.
