Product Description:

1-Phenylglyoxal is an organic compound featuring a phenyl group attached to a glyoxal moiety (α-dicarbonyl group). It is a yellow to orange crystalline solid or powder. This compound is a versatile and reactive bifunctional building block in organic synthesis. Its primary utility lies in its role as a reagent for the selective modification of arginine residues in peptides and proteins, forming a stable condensation product. This property makes it a valuable tool in biochemical research for protein structure-function studies and mapping. Beyond biochemistry, 1-phenylglyoxal serves as a key precursor in heterocyclic chemistry, particularly for the synthesis of various nitrogen-containing heterocycles like imidazoles and quinoxalines, which are scaffolds found in pharmaceuticals and agrochemicals. The compound should be handled with care as it is a lachrymator and can cause skin and eye irritation. It is typically stored under inert atmosphere and at low temperatures to maintain stability.
