186413-76-3 - Introduction
It is an organic compound with the chemical formula C9H8BrN3O3.
Nature:
-Appearance is a white to pale yellow crystalline solid.
-Melting point is about 85-87°C.
-Stable in solid state at room temperature, insoluble in water, soluble in ethanol, acetone and dimethyl sulfoxide.
Use:
-is an important organic synthesis intermediates.
-It can be used in the synthesis of various pesticides, pharmaceuticals and other organic compounds.
Method:
The preparation of the calcium alloy usually requires a multi-step reaction. A commonly used synthesis method includes the following steps:
1. First, under the catalysis of nickel hydride of 3-bromopyridine, methyl acetate and triethylaminoborane react to generate the corresponding alcohol compound.
2. Then, react the alcohol compound obtained in 1 with silver nitrate to obtain calcium.
Safety Information:
It generally does not cause obvious harm to the human body under normal operating conditions, but as an organic compound, you still need to pay attention to the following safety matters:
-Can cause irritation on contact, avoid direct contact with skin, eyes and respiratory tract.
-Good laboratory safety practices, such as wearing protective gloves, goggles and face shields, should be followed during operation.
-Avoid contact with strong oxidants and flammable materials to prevent chemical reactions or fires.
-Store it in a dry place away from fire and high temperature.
