Iminostilbene-d2 CAS 1189918-57-7 chemical structure

Description

Iminostilbene-d2 (CAS 1189918-57-7) is a high-purity analytical reference standard with the molecular formula C14H9D2N and a molecular weight of 195.26 g/mol.

The molecular framework of Iminostilbene-d2 (C14H9D2N) 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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
