4,4′-Methylene-d2-dianiline CAS 215590-72-0

Description

The occurrence of 4,4′-Methylene-d2-dianiline is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4′-Methylene-d2-dianiline (CAS 215590-72-0), molecular formula C13H12D2N2 and molecular weight 200.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4′-Methylene-d2-dianiline (C13H12D2N2) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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), 4,4′-Methylene-d2-dianiline 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.
