The invention relates to a method for producing MoO2Cl2 under inert conditions, comprising the following steps: (i) charging a reaction vessel with MoO2, (ii) reacting the MoO2 in the reaction vessel with the supplied Cl2 at a first temperature T1 to give gaseous MoO2Cl2, (iii) transferring the gaseous MoO2Cl2 into a receiving vessel, (iv) re-sublimating the gaseous MoO2Cl2 in the receiving vessel at a second temperature T2 lower than T1, and (v) recovering the solid-state MoO2Cl2 having a purity of 99.9996 wt.% or more as determined by ICP-OES/MS. The present invention also relates to a method for recovering the solid-state MoO2Cl2 having a purity of 99.9996 wt.% or more as determined by ICP-OES/MS. The invention also relates to high-purity MoO2Cl2, a use thereof, and an electronic component. 本发明是关于一种用于在惰性条件下生产MoO2Cl2的方法，其包含下列步骤：(i)以MoO2装料至反应容器，(ii)在第一温度T1使在该反应容器中的该MoO2与所供应Cl2反应以给出气态MoO2Cl2，(iii)将该气态MoO2Cl2转移到接收容器中，(iv)在该接收容器中以低于T1的第二温度T2将该气态MoO2Cl2再升华，以给出固态MoO2Cl2，以及(v)回收具有通过ICP-OES/MS判定为99.9996wt.％或更高的纯度的固
