Chemical Structure
Description
CATO supplies 3-Bromo-7-methyl-5,6,7,8-tetrahydropyrazolo[5,1-b][1,3]oxazepine (CAS 2409127-76-8), a certified reference material (molecular formula C8H11BrN2O, MW 231.09 g/mol) for analytical method development and quality control.
3-Bromo-7-methyl-5,6,7,8-tetrahydropyrazolo[5,1-b][1,3]oxazepine (C8H11BrN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 3-Bromo-7-methyl-5,6,7,8-tetrahydropyrazolo[5,1-b][1,3]oxazepine 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.
