N-Ethoxycarbonyl maleimide (CAS# 55750-49-7) also known as N-Ethoxycarbonylmaleimide is used to introduce a maleimide group into the structure of a protein, peptide or amino acid. N-Ethoxycarbonylmaleimide can also be used to react with other amine containing compounds for the formation of a maleimide containing compound for later reactions with thiols (-SH). This compound is also useful for reactions involving Diel-Alder processes, Michael additions and other synthetic applications.
LCMS Grade Formic Acid with TFA from CovaChem is of Ultra High Purity ideally suited for sensitive LCMS and HPLC applications. This mixture offers the ability to quickly and easily make one liter of 0.1% Formic Acid with 0.01% TFA enabling the exceptional resolving powers of Trifluoroacetic acid (TFA) without reducing ionization efficiencies.
Maleimide (2,5-Pyrroledione) is a five member ringed compound that is commonly used in synthetic applications and as a synthetic starting material for cysteine blocking, Diels-Alder synthesis, and through Michael addition.
Trifluoroacetic anhydride (CAS# 407-25-0) is an acylation reagent commonly used to derivatize amines, alcohols, amines and phenol functional groups. TFAA derivatives are often made for the sake of improved gas chromatographic resolution and improved detection with ECD detectors.
