Chemical Structure
Description
1-(bromomethyl)-1-ethoxycyclopentane (CAS 1249422-25-0), molecular formula C8H15BrO and molecular weight 207.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(bromomethyl)-1-ethoxycyclopentane (C8H15BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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 1-(bromomethyl)-1-ethoxycyclopentane 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.
