Benzilic Acid
Benzilic acid (2,2-diphenyl-2-hydroxyacetic acid) is a chemically defined organic compound featuring a carboxylic acid group with an alcohol function and two phenyl groups on the alpha carbon. It falls under HTS 2918.17.00.01 as a specific carboxylic acid with alcohol function but without other oxygen functions, matching the chapter's scope for separate organic compounds. Primarily used as a chemical intermediate in pharmaceutical synthesis.
