Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1'-(1,4-Phenylene)bis(N-(4-methoxyphenyl)methanimine) (CAS 3525-51-7) is a high-purity analytical reference standard with the molecular formula C22H20N2O2 and a molecular weight of 344.41 g/mol.
The molecular framework of 1,1'-(1,4-Phenylene)bis(N-(4-methoxyphenyl)methanimine) (C22H20N2O2) is characterized by a steroid core, 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.
CATO manufactures 1,1'-(1,4-Phenylene)bis(N-(4-methoxyphenyl)methanimine) 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.
