Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Cyclohepta[d]imidazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Cyclohepta[d]imidazole (CAS 275-94-5) is a high-purity analytical reference standard with the molecular formula C8H6N2 and a molecular weight of 130.15 g/mol.
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), Cyclohepta[d]imidazole 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.
