1-(TERT-BUTOXY)-4-(2METHOXYETHYL)BENZENE

1-(TERT-BUTOXY)-4-(2METHOXYETHYL)BENZENE is a substituted aromatic compound featuring a benzene ring para-disubstituted with a tert-butoxy group at the 1-position and a 2-methoxyethyl chain at the 4-position. The tert-butoxy moiety introduces steric bulk and ether functionality, while the 2-methoxyethyl substituent incorporates a methoxy group adjacent to an ethyl linkage, conferring polarity and potential hydrogen-bonding capacity. This impurity arises from alkylation or etherification pathways during parent drug synthesis, likely due to competing substitution reactions. It serves as a critical HPLC reference standard for quantifying process-related impurities in pharmaceutical development.
