적용 범위

This standard applies to Mesotrione technical material composed of mesotrione and its production-related impurities. It is mandatory for manufacturers producing and distributing this herbicide technical material in China. It does not apply to formulated pesticide products but strictly regulates the *active ingredient technical material*.

기술 요구 사항

Chapter 3 and Chapter 5 of this standard are mandatory. The standard specifies the physical appearance requirements, requiring the product to be a light brown to yellow-brown solid powder or brown moist solid without visible foreign matter. It establishes critical technical parameters for the active ingredient content, specifically setting minimum limits for the mass fraction of mesotrione calculated on a dry basis. The standard also regulates impurity control, including strict limits for the related impurity nitroxanthone, as well as limits for drying loss and acetone-insoluble substances. Additionally, it mandates specific pH range requirements and outlines comprehensive guidelines for marking, labeling, packaging, storage, and transportation. Compliance with these parameters is essential for market access.

시험 방법

Identification tests utilize Infrared Spectroscopy (IR) and High-Performance Liquid Chromatography (HPLC) to verify the active ingredient. The quantitative determination of mesotrione content is performed using Reversed-Phase HPLC with a UV detector. Impurity testing for nitroxanthone is conducted using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). Other routine tests include vacuum drying for drying loss, pH value determination according to *GB/T 1601*, and acetone-insoluble matter testing per *GB/T 19138*.
