Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If slightly different isomer like ortho- or meta- formyl substitution
Other aromatic carboxylic acids with aldehyde function but not exactly '1-formylphenylacetic acid methyl ester' fall under residual 2918.30.90.
If classified primarily by aldehyde function without ester emphasis
Aldehyde-function compounds of 2906 could apply if ester not considered principal, but chapter notes favor later heading for multi-function compounds.
If it's a sugar ester derivative
Sugar esters and salts of Chapter 29 fall under 2940, but this acyclic aromatic doesn't qualify.
