Description
CATO manufactures 7,7'-((4-Methoxyphenyl)methylene)bis(quinolin-8-ol) 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.
7,7'-((4-Methoxyphenyl)methylene)bis(quinolin-8-ol) (CAS 105192-47-0) is a high-purity analytical reference standard with the molecular formula C26H20N2O3 and a molecular weight of 408.45 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 7,7'-((4-Methoxyphenyl)methylene)bis(quinolin-8-ol) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
