Chemical Structure
Description
2-(4-Bromophenyl)-4-pentyn-2-ol (CAS 85014-12-6), molecular formula C11H11BrO and molecular weight 239.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-Bromophenyl)-4-pentyn-2-ol (C11H11BrO) is characterized by 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. 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.
As a certified reference material (CRM), 2-(4-Bromophenyl)-4-pentyn-2-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
