General Description

Glyoxylic acid hydrate, also known as oxoacetic acid, is a colorless organic compound with the chemical formula C2H4O3. It is a highly reactive and versatile chemical that is used in various industrial applications, including as a key intermediate in the production of pharmaceuticals, agrochemicals, and fine chemicals. It is also used in the manufacture of hair straightening products, dyes, and perfumes. Glyoxylic acid hydrate is a strong organic acid that can undergo various chemical reactions, including esterification, condensation, and oxidation, making it an important building block for the synthesis of a wide range of chemicals and materials. However, due to its corrosive and reactive nature, it should be handled with proper safety precautions and expertise.

Production and Isomeric Distribution of Xanthylium Cation Pigments and Their Precursors in Wine-like Conditions: Impact of Cu(II), Fe(II), Fe(III), Mn(II), Zn(II), and Al(III)

This study establishes the influence of Cu(II), Fe(II), Fe(III), Zn(II), Al(III), and Mn(II) on the oxidative production of xanthylium cations from (+)-catechin and either tartaric acid or glyoxylic acid in model wine systems. The reaction was studied at 25 °C using UHPLC and LC-HRMS for the analysis of phenolic products and their isomeric distribution. In addition to the expected products, a colorless product, tentatively assigned as a lactone, was detected for the first time. The results show the importance of Fe ions and a synergistic influence of Mn(II) in degrading tartaric acid to glyoxylic acid, whereas the other metal ions had minimal activity in this mechanistic step. Fe(II) and Fe(III) were shown to mediate the (+)-catechin-glyoxylic acid addition reaction, a role previously attributed to only Cu(II). Importantly, the study demonstrates that C-8 addition products of (+)-catechin are promoted by Cu(II), whereas C-6 addition products are promoted by Fe ions.
