Sodium 2-diazo-1-naphthol-5-sulfonate Usage And Synthesis

Chemical Properties

yellow powder

Uses

2-Diazo-1-naphthol-5-sulfonic Acid Sodium Salt is a useful research chemical, used in polymer fllms to measure large photoinduced refractive index changes.

General Description

A white to light colored solid substance. Insoluble in water and denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. May ignite and burn with an intense flame if exposed to high temperatures or flame.

Air & Water Reactions

Dust may form an explosive mixture in air. Insoluble in water.

Reactivity Profile

Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. Sodium 2-diazo-1-naphthol-5-sulfonate is a diazo derivative. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
