carbodiimide-activation of carboxylate molecules (seeCarbodiimide Crosslinker Chemistry). NHS ester-activated crosslinkers and labeling compounds react with primary amines in physiologic to slightly alkaline conditions (pH 7.2 to 9) to yield ...
The present invention provides amine/amide catalysts for use in catalyzing the formation of polyurethane. The amine/amide catalysts, which have low fugitivity due to their reactivity with isocyanates, and good catalytic activity, have structure (II) wherein Q is CzH2z+1, or (CH2)nN(R3)kT, ...
NHS ester-activated crosslinkers and labeling compounds react with primary amines in physiologic to slightly alkaline conditions (pH 7.2 to 9) to yield stable amide bonds. The reaction releases N-hydroxysuccinimide (NHS). NHS ester rea...

8 In this process aldehydes or ketones are used to alkylate ammonia and form a primary amine (11), as depicted in equation (11). The reductive step is the reaction of formate with an iminium ion or its equivalent (equation 12).9 (11) (12) Formic acid also reduces stable iminium...
To date, reaction of these reagents with complex peptide mixtures has not been shown. The use of a discreet, highly abundant, low-mass MS/MS signature ion as described in this work provides an unambiguous coding system without introducing additional sources of complexity into the mass spectrum. ...
Figure 1.1.3.Reaction of a primary amine with an isothiocyanate. (Top) Active Esters and Carboxylic Acids Succinimidyl Esters Succinimidyl esters are reliable reagents for amine modification because the amide bonds they form (Figure 1.1.4) are as stable a...
