Chemical Structure
Description
CATO supplies 3-Bromotetrahydro-2H-pyran-2-ol (CAS 103755-65-3), a certified reference material (molecular formula C5H9BrO2, MW 181.03 g/mol) for analytical method development and quality control.
The molecular framework of 3-Bromotetrahydro-2H-pyran-2-ol (C5H9BrO2) 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 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Bromotetrahydro-2H-pyran-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.
