Chemische Eigenschaften
off-white to faint yellowish crystalline powder
Verwenden
Fusaric acid may be used as a derivatizing reagent for the quantification of hydroxysteroids and dehydroepiandrosterone (DHEA)and sulfated DHEA in biological samples using liquid chromatography electrospray-ionization-tandem mass spectrometry (LC/ESI-MS/MS) technique.
Definition
A mycotoxin and picolinic acid, that is an antibiotic and wilting agent that causes yellowing of infected plants.
Allgemeine Beschreibung
Fusaric acid is a novel proton-affinitive derivatizing agent, having an ionization moiety and a hydrophobic moiety. It is commonly used for the derivatization of alcohols and phenols, by liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS).
Hazard
Very toxic.
Sicherheitsprofil
A poison by ingestion,
intraperitoneal, subcutaneous, and
intravenous routes. When heated to
decomposition it emits toxic fumes of NOx.
l?uterung methode
Dissolve it in CHCl3, dry (Na2SO4), filter, evaporate and recrystallise the residue from 50 parts of pet ether (b 40-60o), CHCl3/pet ether or EtOAc, then sublime it in vacuo. The amide crystallises from MeOH with m 128.2-129.0o. The copper salt forms bluish violet crystals from H2O and has m 258-259o.
