Metalaxyl, also known as methyl N-(methoxyacetyl)-N-(2,6-xylyl)-DL-alaninate, is a systemic fungicide with the chemical formula C15H21NO4. It is used to control Pythium and Phytophthora in vegetables. It has suffered a resistance problem going back to the 1980s. Metalaxyl (UV) can be retained and analyzed using the Newcrom B stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with ammonium formate as a buffer. Detection is performed using UV.
The HPLC Method for Analysis of Metalaxyl on Alltesta™ Gradient is designed for Metalaxyl, a pesticide compound. Metalaxyl, also known as methyl N-(methoxyacetyl)-N-(2,6-xylyl)-DL-alaninate, is a systemic fungicide with the chemical formula C15H21NO4.
