2-(4-(TERT-BUTOXY) PHENYL)ETHANOL

2-(4-(Tert-butoxy)phenyl)ethanol is a substituted aryl alcohol featuring a para-tert-butoxyphenyl ring linked to a two-carbon hydroxylated chain. The tert-butoxy group imparts steric bulk and lipophilicity, while the adjacent hydroxyl confers hydrogen-bonding capacity. This compound arises as a synthetic byproduct during alkylation of 4-hydroxyacetophenone with tert-butyl chloride under phase-transfer catalysis. It serves as an HPLC reference standard for quantifying positional isomer impurities in substituted phenethyl alcohol derivatives.
