Properties and stability

Storage method

Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants and food chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills. The “five pairs” management system for extremely toxic substances should be strictly implemented.

Synthesis method

None

Purpose

1. Histochemical determination of lipids (blue or blue-white fluorescence, fades quickly, cannot be used as a permanent specimen). Cancer research.

2. Often used as a pollution indicator substance for carcinogenic polycyclic aromatic hydrocarbons in the environment.

3. It has no production or use value in industry and is generally only discharged with waste as a by-product formed during the production process.

4. Used to calibrate instruments and devices.
