Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Bromo-5-oxaspiro[3.5]Nonane.
CATO supplies 8-Bromo-5-oxaspiro[3.5]Nonane (CAS 1540079-49-9), a certified reference material (molecular formula C8H13BrO, MW 205.09 g/mol) for analytical method development and quality control.
The molecular framework of 8-Bromo-5-oxaspiro[3.5]Nonane (C8H13BrO) 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.
As a certified reference material (CRM), 8-Bromo-5-oxaspiro[3.5]Nonane 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.
