Loteprednol impurity 14 CAS 182068-96-8 chemical structure

Description

Loteprednol impurity 14 (CAS 182068-96-8) is a certified pharmaceutical impurity reference standard with the molecular formula C24H32O7 and a molecular weight of 432.51 g/mol.

Loteprednol impurity 14 (C24H32O7) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Loteprednol impurity 14 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.
