## Abstract C^14^‐labelled O,N‐dimethylhydroxyurethane is synthesized from C^14^‐labelled dimethylsulfate and N‐hydroxy‐urethane. It is further converted without purification into O,N‐^14^‐C‐dimethyl‐hydroxylammoniumchloride, which was then nitrosated with sodiumnitrite in acidic medium to give N‐N

Abstract
The N‐aminooxyacetyl‐N′‐isonicotinoylohydrazine dihydrobromide was labelled with ^14^C in two different positions. In one case we applied a new synthesis route via ^14^C labelled 4‐cyanopyridine and isonicotinic acid. In the other case aminooxyacetic acid was labelled in its carboxyle group.
