Methyl 2-(4-Formylphenyl)acetate
This is the methyl ester of 4-formylphenylacetic acid, a chemically defined aromatic carboxylic acid with both aldehyde and ester oxygen functions. It falls under HTS 2918.30.10.00 as it precisely matches the description of 1-formylphenylacetic acid, methyl ester, which is a specific compound in the subcategory of aromatic carboxylic acids with aldehyde function. Primarily used as an intermediate in pharmaceutical synthesis.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as benzenoid acid ester without emphasizing aldehyde function
Could be seen as aromatic acid ester of Chapter 2916 if aldehyde is not principal function, but Chapter 29 note prioritizes later numerical heading.
If containing heterocyclic ring structure
Heterocyclic compounds with oxygen function fall under 2932, shifting from acyclic aromatic carboxylic acid classification.
If imported as mixture with solvents or impurities exceeding chapter purity standards
Chapter 29 excludes mixtures; impure forms or solutions not meeting 'separate chemically defined' criteria go to mixtures of Chapter 38.
