5-Ethynylindoline CAS 1849377-90-7 chemical structure

Description

CATO supplies 5-Ethynylindoline (CAS 1849377-90-7), a certified reference material (molecular formula C10H9N, MW 143.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C10H9N, 5-Ethynylindoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 143.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 5-Ethynylindoline 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.
