This document specifies the requirements, safety information, sampling, test methods, inspection rules, as well as marking, labeling, packaging, transportation, and storage of 3-chloro-2-methylaniline.
This document is applicable to the quality control of 3-chloro-2-methylaniline products.
The moisture content (mass fraction) in 3-chloro-2-methylaniline standard is ≤ 0.20%. The determination of moisture in dyes and dye intermediates using GB/T 2386-2006 is complex, time-consuming, labor-intensive, and inefficient, which cannot meet the needs of industrial production testing and is limited in use.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a gas chromatography method for the determination of trace moisture in 3-chloro-2-methylaniline products. The method is quantitative using an area external standard method, and the results are satisfactory.
