Chemical Structure
Description
As a certified reference material (CRM), 5-(Bromomethyl)-3-methyl-4,5-dihydro-1,2-oxazole 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.
5-(Bromomethyl)-3-methyl-4,5-dihydro-1,2-oxazole (CAS 68843-63-0) is a high-purity analytical reference standard with the molecular formula C5H8BrNO and a molecular weight of 178.03 g/mol.
The molecular framework of 5-(Bromomethyl)-3-methyl-4,5-dihydro-1,2-oxazole (C5H8BrNO) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
