Application

Phenylglyoxylic acid can be used as a precursor in the synthesis of:
  • O-acyl acetanilides by decarboxylative o-acylation of acetanilides using Pd catalyst.
  • Phenylhydroxycarbene by high-vacuum flash pyrolysis.
  • 2-arylbenzothiazoles by reacting with o-aminothiophenol using ammonium niobium oxalate (ANO) as a catalyst.
  • 3-aryl-2H-benzo[b][1,4]benzoxazin-2-ones by treating with o-aminophenol in the presence of ammonium niobium oxalate catalyst.
  • 2-aryl benzothiazoles through potassium persulfate (K2S2O8)-mediated oxidative condensation of benzothiazoles.

Associations between occupational styrene exposure and impairment of hearing function were investigated, guided by three questions: are there hearing losses concerning high frequency and standard audiometric test? Are there dose-response relationships and measurable thresholds of effects? Are there signs of
