Chemical Structure

Melitracen Impurity 3 CAS 5447-86-9 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, Melitracen Impurity 3 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.28 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).

As a process- or degradation-related impurity, Melitracen Impurity 3 (CAS 5447-86-9, C16H14O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Melitracen Impurity 3 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.
