Chemical Structure

Ethacridine Lactate Impurity 10 CAS 5568-33-2 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 Ethacridine Lactate Impurity 10.

Ethacridine Lactate Impurity 10 (CAS 5568-33-2) is a certified pharmaceutical impurity reference standard with the molecular formula C7H4ClNO3 and a molecular weight of 185.56 g/mol.

The molecular framework of Ethacridine Lactate Impurity 10 (C7H4ClNO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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 Ethacridine Lactate Impurity 10 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.
