Chemical Structure
Description
As a certified reference material (CRM), 4-(((2-Bromocyclopentyl)oxy)methyl)tetrahydro-2h-pyran 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.
4-(((2-Bromocyclopentyl)oxy)methyl)tetrahydro-2h-pyran (CAS 1248813-06-0), molecular formula C11H19BrO2 and molecular weight 263.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(((2-Bromocyclopentyl)oxy)methyl)tetrahydro-2h-pyran (C11H19BrO2) 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. 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.
