Description

General description

Maleic anhydride is a dehydration product of maleic acid that is of considerable industrial importance.

Application

Maleic anhydride has been used as a reference standard for the determination of the analyte in:
• Workplace air samples by capillary gas chromatography combined with electron capture detection (GC-ECD).

It may be used as a derivatization agent for fatty alcohol ethoxylates in:
• Industrial mixtures, cleaning products and river and sea waters by high performance liquid chromatography (HPLC) coupled with ultraviolet-visible (UV-Vis) diode array detection (DAD).

Other Notes

For the complete dissociation of enzymes into soluble subunits; For the reversible blocking of amino groups (lysine reagent); P.J.G. Butler, J.I. Harris, B.S. Hartley, R. Lebermann; For the maleylation of proteins
