Iminostilbene-d2DISCONTINUED, offer I445004 CAS 91704-65-3

Description

The occurrence of Iminostilbene-d2DISCONTINUED, offer I445004 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.

Iminostilbene-d2DISCONTINUED, offer I445004 (CAS 91704-65-3), molecular formula C14H9D2N and molecular weight 195.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Iminostilbene-d2DISCONTINUED, offer I445004 (C14H9D2N) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 195.26 g/mol, it falls into the medium-molecular-weight range. 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.
