5,7-dihydroxy-2-(4-hydroxyphenyl)-3-methoxy-6-(3-methylbut-2-enyl)chromen-4-one - Introduction
TOPAZOLIN, also known as TOPAZOLIN, is an organic compound. The following is a description of the nature, use, formulation and safety information of TOPAZOLIN:
Nature:
The chemical formula of TOPAZOLIN is C17H19NO4, and its appearance is yellow crystalline powder. It is an organic base, soluble in ethanol and ether, but practically insoluble in water. It is combustible, and its combustion produces toxic nitrogen oxides.
Use:
TOPAZOLIN is often used as an indicator in chemical laboratories, especially in redox reactions. It may change from blue-violet to colorless, or from colorless to blue-violet depending on the change in the acid-base properties of the reaction liquid, thereby indicating the progress of the reaction.
Method:
TOPAZOLIN can be obtained by synthesis. A common method of preparation is the condensation of pyridine-2-carbaldehyde with methacrylates to give TOPAZOLIN.
Safety Information:
TOPAZOLIN has irritating and corrosive properties. During use, wear protective gloves and glasses to avoid direct contact with skin and eyes. At the same time, it should be operated in a well-ventilated place to avoid inhaling its powder. Keep away from ignition and oxidizing agents during use and storage. If TOPAZOLIN is ingested or inhaled by mistake, seek medical attention immediately.
