5-Hydroxy-6-[[2-methoxy-5-[[2-(sulfooxy)ethyl]sulfonyl]phenyl]azo]-1-naphthalenesulfonic acid disodium salt - Introduction
disodium 5-hydroxy-6-[[2-methody-5-[[2-(sulfonatooxy) ethyl] sulfonyl] phenyl]azo] napthalenesulfonate is an organic dye, the chemical name is disodium salt 5-hydroxy-6-[[2-methoxy-5-[[2-(sulfonyloxy) ethyl] sulfonyl] phenyl]azo]naphthalene sulfonate. The following is an introduction about the nature, usage, formulation and safety information of disodium 5-hydroxy-6-[[2-methody-5-[[2-(sulfonatooxy) ethyl] sulfonyl] phenyl]azo] napthalenesulphonate:
Properties: disodium 5-hydroxy-6-[[2-methody-5-[[2-(sulfonatooxy) ethyl] sulfonyl] phenyl]azo] napthalensulphonate is a red powdery solid, soluble in water, it has good stability.
Usage: disodium 5-hydroxy-6-[[2-methoxy-5-[[2-(sulfonatooxy) ethyl] sulfonyl] phenyl]azo] napthalenesulfonate is a kind of widely used in textile, printing and dyeing, dyes for industries such as leather. It can be used for dyeing textiles, dyeing leather, color inks and coatings, etc. disodium 5-hydroxy-6-[[2-methody-5-[[2-(sulfonatooxy) ethyl] sulfonyl] phenyl]azo] napthalene is also used as a biomarker, indicator, and chromogenic reagent for compound analysis.
Preparation method: The preparation of disodium 5-hydroxy-6-[[2-methody-5-[[2-(sulfonatooxy) ethyl] sulfonyl] phenyl]azo] napthalenesulphonate is generally carried out by an azo coupling reaction. First, 5-hydroxy-2-aminonaphthalenesulfonic acid is reacted with sodium 2-ethoxysulfoethanesulfonate to give the corresponding azoammonium salt. Then, by reaction with 2-methoxyaniline sulfoacetaldehyde, disodium 5-hydroxy-6-[[2-methoxy-5-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl]azo]naphthalenesulphonate dye molecular structure.
Security information: disodium 5-hydroxy-6-[[2-methody-5-[[2-(sulfonatooxy) ethyl] sulfonyl] phenyl]azo] napthalenesulphonate has relatively high security, however, care should be taken to avoid inhalation of dust, contact with skin and eyes. In the process of use, should wear protective glasses, wear protective clothing and gloves, to ensure good ventilation. In case of accidental contact, rinse immediately with plenty of water. At the same time, storage should avoid contact with oxidants and strong acids.
