Chemical Structure
Description
The occurrence of Benzyl 7-bromo-2-naphthoate is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Benzyl 7-bromo-2-naphthoate (CAS 2497586-41-9), molecular formula C18H13BrO2 and molecular weight 341.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzyl 7-bromo-2-naphthoate (C18H13BrO2) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine 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.
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 Benzyl 7-bromo-2-naphthoate 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.
