Chemical Structure

2,3-Dihydro-1H-pyrrole CAS 638-31-3 chemical structure

Description

The occurrence of 2,3-Dihydro-1H-pyrrole is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,3-Dihydro-1H-pyrrole (CAS 638-31-3), a certified reference material (molecular formula C4H7N, MW 69.11 g/mol) for analytical method development and quality control.

The molecular framework of 2,3-Dihydro-1H-pyrrole (C4H7N) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 2,3-Dihydro-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.
