2,4-Dichlorobenzenediazoniumtetrafluoroborate - Introduction

2, is an organic compound with the chemical formula C6H3Cl2N2BF4.

Nature:
2, is a solid substance, colorless to white crystals, soluble in organic solvents such as ethyl acetate and ketone. It is relatively stable at low temperatures, but may be unstable at higher temperatures or under humid conditions.

Use:
2, is mainly used as an intermediate in organic synthesis. It can be reduced to the corresponding aromatic amine, or with other organic coupling reaction (such as piperazine reaction), to synthesize new compounds.

Method:
Preparation 2, usually by the following steps:
1. React 2,4-dichlorobenzene diazo compound with excess tetrafluoroboric acid to generate 2, fluoroboric acid.
2. Further treatment and purification, such as crystallization and washing, to obtain pure product.

Safety Information:
2, must be operated under appropriate laboratory conditions. Avoid contact with skin, eyes and inhalation of dust or gas during operation. It may be irritating and sensitizing to the eyes and skin.
