Compared with other compounds in its class, the molecular weight of 141.17 g/mol gives 3-Ethynyl-1h-indole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Ethynyl-1h-indole (CAS 62365-78-0), a certified reference material (molecular formula C10H7N, MW 141.17 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3-Ethynyl-1h-indole is typically pale yellow to yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.17 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), 3-Ethynyl-1h-indole 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.
