3-Oxocyclobutanecarboxylic acid (CAS 23761-23-1) is a strained cyclic beta-keto acid used primarily as a specialized intermediate in pharmaceutical synthesis. Its core production involves the decarboxylation of substituted cyclobutane derivatives or catalytic oxidation of cyclobutene carboxylic acids.
Store under inert atmosphere at low temperatures to prevent thermal decarboxylation. Use appropriate PPE including gloves and eye protection due to potential irritant properties; avoid ingestion and inhalation of dust.
