Chemical Structure

Amphotericin B Impurity 1(Amphotericin B Methyl Ester) CAS 36148-89-7 chemical structure

Description

Amphotericin B Impurity 1(Amphotericin B Methyl Ester) (C48H75NO17) contains a nitrogen-containing heterocyclic scaffold, an amide group, 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).

Amphotericin B Impurity 1(Amphotericin B Methyl Ester) (CAS 36148-89-7) is a certified pharmaceutical impurity reference standard with the molecular formula C48H75NO17 and a molecular weight of 938.11 g/mol.

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 Amphotericin B Impurity 1(Amphotericin B Methyl Ester) 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.
