N-Methylpyrrole-d4 (ring-d4) CAS 190386-37-9

Description

As a certified reference material (CRM), N-Methylpyrrole-d4 (ring-d4) 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.

N-Methylpyrrole-d4 (ring-d4) (CAS 190386-37-9), molecular formula C5H3D4N and molecular weight 85.14 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H3D4N, N-Methylpyrrole-d4 (ring-d4) contains deuterium isotope labeling, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 85.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
