Chemical Structure
Description
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.
4-Allyl-4-(bromomethyl)tetrahydro-2H-pyran (CAS 1881925-04-7) is a high-purity analytical reference standard with the molecular formula C9H15BrO and a molecular weight of 219.12 g/mol.
The molecular framework of 4-Allyl-4-(bromomethyl)tetrahydro-2H-pyran (C9H15BrO) 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.
As a certified reference material (CRM), 4-Allyl-4-(bromomethyl)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.
