Chemical Structure
Description
1-(2-Bromo-1-(tert-butoxy)ethyl)-2-methoxybenzene (CAS 1248008-32-3), molecular formula C13H19BrO2 and molecular weight 287.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-Bromo-1-(tert-butoxy)ethyl)-2-methoxybenzene (C13H19BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(2-Bromo-1-(tert-butoxy)ethyl)-2-methoxybenzene 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.
