Scope

Scope: This standard specifies the requirements, test methods, inspection rules, and marking, labeling, packaging, and storage for 1% Emamectin Benzoate Microemulsion. This standard applies to 1% Emamectin Benzoate Microemulsion prepared from standard Emamectin Benzoate API, co-solvents, surfactants, and water. The other names, structural formulas, and basic physical and chemical parameters of the active ingredient of this product are as follows: ISO common name: Emamectin Benzoate Chemical name: 4’’-Epoxy-Emamectin Benzoate Main technical content: 4.4 Determination of Emamectin Benzoate Content 4.4.1 Method Summary The sample is dissolved in methanol, and the mobile phase is acetonitrile + triethylamine + methanol + water. A stainless steel column filled with ODSC18 and a variable wavelength UV detector are used for high-performance liquid chromatography separation and determination of Emamectin Benzoate, with external standard method used for quantification. 4.4.2 Reagents and Solutions a) Acetonitrile: chromatographically pure; b) Methanol: filtered through a 0.45μm filter membrane; c) Triethylamine: chromatographically pure; d) Emamectin Benzoate standard: with a known content of ≥95.0%; e) Water: freshly distilled and double-distilled water. 4.4.3 Instrumentation a) High-performance liquid chromatograph with a variable wavelength UV detector; b) Chromatography data processor; c) Chromatography column: 250mm × 4.6mm (id) stainless steel column, filled with ODSC18, with a pore size of 5μm; d) Micro-injection pump: 10μL. 4.4.4 Chromatography Operating Conditions a) Column temperature: room temperature; b) Mobile phase: acetonitrile + water + methanol + triethylamine = 479 + 33.3 + 2 + 0.1 (v/v); c) Flow rate: 1.0mL/min; d) Detection wavelength: 245nm; e) Injection volume: 3μL; f) Retention time: Emamectin Benzoate approximately 11.4min (see Figure 1). The above operating conditions are typical parameters. Analysts can adjust these parameters according to the chara
