Products classified under HTS 2918.17.00.01
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.
Benzilic Acid Anhydride
The cyclic anhydride derivative of benzilic acid, a white crystalline solid used in organic synthesis. Classified under HTS 2918.17.00.01 as it derives directly from the named carboxylic acid with alcohol function, per chapter provisions for anhydrides. Employed in producing pharmaceuticals and as a reagent in laboratory settings.
Benzilic Acid Pharmaceutical Grade
High-purity benzilic acid (≥99.5%) meeting USP/EP standards for use as intermediate in anticholinergic drug synthesis like benactyzine. Falls under HTS 2918.17.00.01 as a separate chemically defined compound with the specified carboxylic-alcohol structure. Essential for manufacturing medications treating motion sickness and Parkinson's symptoms.
Benzilic Acid with Stabilizer
Benzilic acid containing added stabilizer (e.g., 0.1% citric acid) for preservation during storage/transport. Qualifies under HTS 2918.17.00.01 per chapter note (f) as the stabilizer is necessary and does not alter general use suitability. Used in industrial chemical processes requiring long-term stability.
Benzilic Acid Sodium Salt
Sodium benzilate, the sodium salt of 2,2-diphenyl-2-hydroxyacetic acid, used in coordination chemistry. Classified in HTS 2918.17.00.01 per chapter note 3(C)(1) as inorganic salt of the organic acid compound. Applied in synthesis of metal-organic frameworks and as analytical reagent.
Benzilic Acid Research Grade
Ultra-high purity benzilic acid (99.9%) for laboratory research and NMR reference standards. Meets HTS 2918.17.00.01 as chemically defined with no impurities affecting classification. Supplied in small quantities for academic and R&D applications.
Benzilic Acid Technical Grade
Technical grade benzilic acid (95-98% purity) for industrial synthesis applications. Remains under HTS 2918.17.00.01 as chemically defined organic compound despite minor impurities not constituting mixtures. Used in large-scale production of quaternary ammonium compounds.
