Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1′-[Methylenebis(4,1-phenylenenitrilomethylidyne)]bis[2-naphthalenol].
1,1′-[Methylenebis(4,1-phenylenenitrilomethylidyne)]bis[2-naphthalenol] (CAS 4231-45-2) is a high-purity analytical reference standard with the molecular formula C35H26N2O2 and a molecular weight of 506.59 g/mol.
The molecular framework of 1,1′-[Methylenebis(4,1-phenylenenitrilomethylidyne)]bis[2-naphthalenol] (C35H26N2O2) 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.
CATO manufactures 1,1′-[Methylenebis(4,1-phenylenenitrilomethylidyne)]bis[2-naphthalenol] under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
