Semicarbazide hydrochloride, 99%, Thermo Scientific Chemicals

Description

Urease substrate and MAO inhibitor

Semicarbazide hydrochloride is used as urease substrate and MAO inhibitor. Derivatizing agent for carbonyl compounds as their semicarbazones which produces crystalline compounds with characteristic melting points. Also used in heterocyclic synthesis. Semicarbazone formation has been used to separate carbonyl compounds from mixtures by adsorption onto silica gel from a hydrocarbon solution. Regeneration is by hydrolysis with oxalic acid.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
