Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 195.26 g/mol gives 1,5-Dimethyl-9H-carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,5-Dimethyl-9H-carbazole (CAS 51640-60-9), molecular formula C14H13N and molecular weight 195.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1,5-Dimethyl-9H-carbazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 195.26 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.
As a certified reference material (CRM), 1,5-Dimethyl-9H-carbazole 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.
