What is Hinsberg reagent?
Benzene sulphonyl chloride $\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{SO}_2 \mathrm{Cl}\right)$ is known as Hinsberg reagent. It is used to distinguish between primary, secondary and tertiary amine.
Why is benzene diazonium chloride not stored and is used immediately after its preparation?
Benzene diazonium chloride are highly unstable and stable for a very short time span in solution at low temperature. Due to its instability, it is used immediately after its preparation.
