Description and Uses
Semicarbazide (SM) is a metabolite of the nitrofurane Nitrofurazone (5-nitro-2- furaldehyde-semicarbazone), used as indicator to detect the use of nitrofurazone in food-producing animals
due to their carcinogenic properties the use of nitrofurans is prohibited within the EU in animal breeding (Commission Regulation 37/2010) .
to harmonise the detection of semicarbazide a Minimum Required Performance Limit (MRPL) of 1 µg/kg is set within the EU (Commission Decision 2003/181).
Semicarbazide is used as a potent nucleophile; forms many crystalline carbonyl derivatives.
