Description: Maleimides are among the most frequently used reagents for thiol modification. In most proteins, the site of reaction is at cysteine residues that either are intrinsically present or result from reduction of cystines. Unlike iodoacetamides, maleimides do not react with histidines and methionines under physiological conditions. Fluorescein-5-maleimide is one of the most popular fluorescent dyes for thiol modifications of proteins.

Description: Product Description2-Amino-3-formylchromone (2-Amino-4-oxo-4H-1-benzopyran-3-carboxaldehyde) is a benzopyran derivative. It is a bicyclic heterocyclic molecule made up of a benzene ring fused to a heterocyclic pyran ring. It undergoes condensation with (R)-2-amino-2-phenylethanol to afford Schiff base ligand, which forms complexes with Cu(NO3)2 and Zn(NO3)2Product Application2-Amino-3-formylchromone may be used in the preparation of the following:• chiral Schiff base ligands (R)/(S)-2-amino-3-(((1-hydroxypropan-2-yl)imino)methyl)-4H-chromen-4-one• hydrazone derivatives, required for the synthesis of heterocyclic Schiff′s bases having antimicrobial activity[• N-{4-[(6-chloro-4-oxo-4H-chromen-3-ylmethylene)amino]phenyl}-3,5-dimethyl-benzofuran-2-carboxamide• N-{4-[(6-chloro-4-oxo-4H-chromen-3-ylmethylene)amino]phenyl}-1,4-dihydro-chromono [2,3-b]pyrrole-2-carboxamide• 6-chloro-3-{[4-(2-thioxo-3,6-dihydro-2H-1,3,4-thiadiazin-5-ylamino)phenylimino] methyl}- 4-oxo-4H -chromene• 3¬-(2-amino¬-4¬-oxo¬-4H¬-chromen¬-3-¬yl)methylidene)¬-6-¬ ethyl-¬2H-¬pyrano[3,2-¬c]quinolone-¬2,4,5(3H,6H)-trione
