Chemical Structure
Description
As a certified reference material (CRM), 6'-Bromo-1',3'-dihydrospiro[cyclohexane-1,2'-imidazo[4,5-b]pyridine] 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-1',3'-dihydrospiro[cyclohexane-1,2'-imidazo[4,5-b]pyridine] (CAS 161263-64-5) is a high-purity analytical reference standard with the molecular formula C8H6ClF3 and a molecular weight of 194.58 g/mol.
Owing to fluorine/chlorine substitution, an aromatic ring system, 6'-Bromo-1',3'-dihydrospiro[cyclohexane-1,2'-imidazo[4,5-b]pyridine] is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
