GB/T 4840-2016 "Nitroanilines" is applicable to the quality control of products such as o-nitroaniline, m-nitroaniline, and p-nitroaniline. It specifies technical requirements, test methods, etc. Melting point is determined using a melting point apparatus, purity is measured with a spectrophotometer, and acidity is tested with a titrator, among other indicators. The standard clearly defines the testing conditions and result evaluation criteria for each item, providing a unified basis for the production and acceptance of nitroaniline products.
