Common NameTW94a
Description1-(2,4-Dihydroxy-6-methylphenyl)ethanone belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. TW94a was first documented in 2023 (PMID: 36125461). 1-(2,4-Dihydroxy-6-methylphenyl)ethanone is an extremely weak basic (essentially neutral) compound (based on its pKa).
