General description

7-(Diethylamino)coumarin-3-carbohydrazide is a coumarin-hydrazide reagent typically used as a fluorescent chemical probe for labeling of cellular carbonyls.

Application

7-(Diethylamino)coumarin-3-carbohydrazide is used for derivatization and detection of carboxylic acid and carbonylated molecules such as lipid peroxidation products (LPP) by electrospray ionization-mass spectrometry (ESI-MS) in positive ion mode. It may be used as a fluorescent label for the determination of lipid aldehydes in food products by normal phase liquid chromatography (NPLC) coupled to ESI-MS and fluorescent detector (FLD) and for the derivatization of monoterpene alcohols in urine prior to analysis by high performance liquid chromatography(HPLC) with FLD coupled to ESI-MS.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

A method was developed for the determination of the monoterpene alcohols verbenol, myrtenol, perillyl alcohol, alpha-terpineol, Delta(3)-carene-10-ol, thymol and p-alpha,alpha-trimethylbenzylalcohol in urine samples. After an enzymatic cleavage of their glucuronide- and sulfate conjugates the monoterpene alcohols were converted in the

7-Diethylaminocourmarin-3-carbohydrazide was used to label the ketone group of the tetrahydroprogesterones to form fluorescent derivatives with high sensitivity. The four isomeric 3-hydroxypregnanes separated readily on high-performance, thin-layer chromatography after derivatization. This separation was not possible with the underivatized isomers. Standards
