N1,N5-Bis(pyridin-4-ylmethylene)naphthalene-1,5-diamine CAS 757947-79-8

Description

Compared with other compounds in its class, the molecular weight of 336.39 g/mol gives N1,N5-Bis(pyridin-4-ylmethylene)naphthalene-1,5-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N1,N5-Bis(pyridin-4-ylmethylene)naphthalene-1,5-diamine (CAS 757947-79-8), molecular formula C22H16N4 and molecular weight 336.39 g/mol, is a CATO reference standard with documented purity and traceability.

N1,N5-Bis(pyridin-4-ylmethylene)naphthalene-1,5-diamine (C22H16N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
