Chemical Structure

1-(2-Methylbut-3-yn-2-yl)-1h-pyrrole CAS 646989-37-9 chemical structure

Description

As a certified reference material (CRM), 1-(2-Methylbut-3-yn-2-yl)-1h-pyrrole 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.

1-(2-Methylbut-3-yn-2-yl)-1h-pyrrole (CAS 646989-37-9) is a high-purity analytical reference standard with the molecular formula C9H11N and a molecular weight of 133.19 g/mol.

The molecular framework of 1-(2-Methylbut-3-yn-2-yl)-1h-pyrrole (C9H11N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
