Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.12 g/mol gives Ethyl 2-bromo-2-(p-tolyl)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-bromo-2-(p-tolyl)acetate (CAS 15674-78-9), molecular formula C11H13BrO2 and molecular weight 257.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-bromo-2-(p-tolyl)acetate (C11H13BrO2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Ethyl 2-bromo-2-(p-tolyl)acetate 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.
