Chemical Structure
Description
1-(Benzyloxy)-4-bromo-3-chloro-2-fluorobenzene (CAS 1881330-85-3), molecular formula C13H9BrClFO and molecular weight 315.57 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system, 1-(Benzyloxy)-4-bromo-3-chloro-2-fluorobenzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 315.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-(Benzyloxy)-4-bromo-3-chloro-2-fluorobenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
