Description

General description

Tin(II) chloride (SnCl₂), also known as stannous chloride, is commonly used as a reducing agent.

Application

Synthesis of tin(IV) octaethylcorroles was accomplished with this reagent. These new compounds exhibit reversible oxidation only at the conjugated ring system, not at the metal center.

Tin(II) chloride (SnCl₂) has been used to label compounds with ^99mtechnetium (^99mTc).
