General description

Methyl-2-benzoylbenzoate is a 2-acylarylcarboxylate.
  • It can undergo asymmetric transfer hydrogenation reaction in propanol in the presence of a Ruthenium catalyst.
  • Methyl-2-benzoylbenzoate is formed as one of the reaction products during the reaction between methyl benzoate and lithium 2,2,6,6-tetramethylpiperidide (LiTMP) at -117°C.
  • Methyl-2-benzoylbenzoate can be synthesized from the reaction between corresponding 2-substituted benzoic acid and thionyl chloride in methanol.

A recent in vitro study reported that the photoinitiator 2-isopropylthioxanthone (2-ITX) is an endocrine-disrupting compound (EDC). However, it is not clear whether other photoinitiators such as 1-hydroxycyclohexyl phenyl ketone (1-HCHPK) and 2-methyl-4'-(methylthio)-2-morpholinopropiophenone (MTMP) produce endocrine-disrupting effects. The purpose of this
