6'-Bromo-4,4-difluoro-8'-methyl-2'H-spiro[cyclohexane-1,3'-imidazo[1,5-a]pyridine]-1',5'-dione CAS 1849592-64-8

Description

As a certified reference material (CRM), 6'-Bromo-4,4-difluoro-8'-methyl-2'H-spiro[cyclohexane-1,3'-imidazo[1,5-a]pyridine]-1',5'-dione 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.

6'-Bromo-4,4-difluoro-8'-methyl-2'H-spiro[cyclohexane-1,3'-imidazo[1,5-a]pyridine]-1',5'-dione (CAS 1849592-64-8) is a high-purity analytical reference standard with the molecular formula C13H13BrF2N2O2 and a molecular weight of 347.16 g/mol.

Based on its molecular formula C13H13BrF2N2O2, 6'-Bromo-4,4-difluoro-8'-methyl-2'H-spiro[cyclohexane-1,3'-imidazo[1,5-a]pyridine]-1',5'-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 347.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
