This standard specifies the quality control requirements for H-acid monosodium salts (1-naphthylamine-8-hydroxy-3,6-disulfonic acid monosodium salts), including its sampling, test methods, inspection rules, marking, labeling, Encasement, transportation and storage. The molecular formula of H-acid monosodium salts is C < unk > H < unk > NO < S < unk > Na, the relative molecular mass is 341.30 (according to the international relative atomic mass in 2009), and the CAS number is 5460-09-3. The purpose of this standard is to ensure the mass qualification of H-acid monosodium salts in production and use. The normative documents involved include the preparation and determination methods of chemical reagents, the general rules for sampling chemical products, and the specifications and test methods for analyzing laboratory water. Ensure that it meets relevant safety and mass standards.
