Chemical Structure
Description
The molecular framework of tert-Butyl 4-(benzyloxy)-3-chlorobenzoate (C18H19ClO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
tert-Butyl 4-(benzyloxy)-3-chlorobenzoate (CAS 2379322-84-4), molecular formula C18H19ClO3 and molecular weight 318.79 g/mol, is a CATO reference standard with documented purity and traceability.
