4-Benzofurazancarboxaldehyde - Introduction
The chemical formula is C8H5N3O2, which is an organic compound. Its properties are as follows:
1. Appearance: White to light yellow solid.
2. Solubility: soluble in organic solvents such as alcohol, ether and ketone, insoluble in water.
The main uses of calcium include the following:
1. Chemical reagents: as an important intermediate for the synthesis of other compounds.
2. Luminescent materials: with fluorescent properties, can be used for research and application in the field of optoelectronic devices.
3. Biomarkers: can be used as the detection and labeling of certain biological molecules.
There are several main methods of preparation:
1. Redox reaction: React an appropriate amount of benzoxadiazole with chloric acid under acidic conditions, and then use sodium nitrite to reduce the resulting benzoxadiazole derivative to fluorite.
2. Reaction coupling method: through the reaction of benzyl sodium sulfate and sodium cyanide, benzoxadiazole-4-sodium sulfate is generated, and then it is reacted with hydrochloric acid to obtain benzoxadiazole-4-sodium sulfate.
However, please note the following safety information:
1. The eye and skin irritation, contact should pay attention to the use of personal protective equipment.
2. May cause allergic reactions, it can not be excessive exposure to the smell or dust.
3. It should be used in a well-ventilated place and avoid inhalation or intake.
4. Should be properly stored, away from fire, heat and oxidant.
5. Please comply with the relevant safety procedures and guidelines.
