3-INDOXYL PHOSPHATE DISODIUM SALT Usage And Synthesis

Chemical Properties

White to Off-White Powder

Uses

A useful histochemical substrate for alkaline phosphatase

Uses

A histochemical substrate for alkaline phosphatase

General Description

White to off-white powder.

Air & Water Reactions

If left exposed to air for more than 120 minutes, 3-INDOXYL PHOSPHATE DISODIUM SALT will turn to blue then black within 6 hours. Water soluble.

Reactivity Profile

3-INDOXYL PHOSPHATE DISODIUM SALT is incompatible with oxidizing agents. 3-INDOXYL PHOSPHATE DISODIUM SALT is hydrolyzed rapidly by alkaline phosphatase to form a compound which is readily oxidized in solution by ambient oxygen under basic environment.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition 3-INDOXYL PHOSPHATE DISODIUM SALT emits toxic fumes of nitrogen oxides, phosphoric acid, carbon monoxide and carbon dioxide.

Fire Hazard

Flash point data for 3-INDOXYL PHOSPHATE DISODIUM SALT are not available; however, 3-INDOXYL PHOSPHATE DISODIUM SALT is probably combustible.
