Chemical Structure
Description
The occurrence of Copper(II) (E)-1-(pyridin-2-yldiazenyl)naphthalen-2-olate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Copper(II) (E)-1-(pyridin-2-yldiazenyl)naphthalen-2-olate (CAS 23299-85-6), molecular formula C15H10N3OCu and molecular weight 311.81 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Copper(II) (E)-1-(pyridin-2-yldiazenyl)naphthalen-2-olate (C15H10N3OCu) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
