Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-4-[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-methoxybenzene (CAS 1133116-37-6), molecular formula C13H21BrO2Si and molecular weight 317.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-4-[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-methoxybenzene (C13H21BrO2Si) is characterized by a carboxylic acid group, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-Bromo-4-[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-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.
