Methyl Diphenylglycolate
Methyl diphenylglycolate, synonymous with methyl benzilate, is a white crystalline powder that is the methyl ester derivative of benzilic acid. Classified under HTS 2918.19.1100 due to its aromatic structure and specific identification in the tariff schedule for benzilic acid methyl ester. Primarily serves as a synthetic intermediate in organic chemistry.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by its alcohol function without acid emphasis
Alcohol priority compounds with --C(OH)< groups may fall under 2906 if not specifically carboxylic acid derivatives per chapter notes.
If containing a saturated acyclic structure
Non-aromatic versions shift to heading 2915 for saturated acyclic carboxylic acids with alcohol function.
If a sugar ester derivative
Sugar esters and salts of Chapter 29 acids classify under 2940 per note 2(c).

Methyl Benzilate
Methyl benzilate is the methyl ester of benzilic acid, a chemically defined aromatic carboxylic acid with alcohol function but without other oxygen function. It falls under HTS 2918.19.1100 as a specific enumerated product in the subcategory for aromatic derivatives. This compound is typically used as an intermediate in pharmaceutical synthesis.
Benzilic Acid Methyl Ester USP Grade
USP-grade benzilic acid methyl ester is a high-purity form of this aromatic compound used in pharmaceutical research and API synthesis. It qualifies for HTS 2918.19.1100 as the specifically named methyl ester of benzilic acid, meeting Chapter 29's criteria for separate chemically defined organic compounds. The USP designation ensures compliance with pharmacopeia standards.
Diphenyl(hydroxy)acetic Acid Methyl Ester
This systematic name refers to methyl benzilate, an aromatic carboxylic acid ester with a hydroxy group, precisely matching HTS 2918.19.1100's description. It is a key intermediate in antihistamine and anticholinergic drug production. Chapter 29 notes confirm its place among acid-function compounds with alcohol function.
Methyl Benzilate Technical Grade
Technical-grade methyl benzilate contains minor impurities but remains a separate chemically defined compound per Chapter 29 note (a), classifying under HTS 2918.19.1100. Used in industrial organic synthesis for dyes and polymers. The specific naming in the tariff overrides general purity concerns.
