50 % solution is stable at room temperature for several months.
No
study performed at pH 4, 7 and 9, as according to our knowledge,
solution is stable for a range of pH from 0.3 to 0.8. Beyond it become
sensible to the Cannizaro reaction, which slowly degrades glyoxylates in
glycolate and Oxalate.
Glyoxylic acid is an aldehyde without hydrogen atome in alpha position
of carbonyl. It undergoes dismutation reaction during which one molecule
of glyoxylic acid is oxidated to form oxalic acid and another one is
reduced to form glycolic acid.
