Glyoxalic acid can be used in the synthesis of a variety of reactions.
Glyoxylic acid is used in Hopkins Cole reaction, which is used in the detection of tryptophan in proteins.
It reacts with phen0l to get 4-hydroxymandelic acid, which on further reaction with amm0nia gives hydroxyphenylglycine, as a precursor to the drug amoxicilln.
It is also used as a starting material for the preparation of 4-hydroxyphenylacetic acid, which is used to get atenolo.
