Eravacycline Impurity 7(TP-498） CAS CATO-C4X-29387 chemical structure

Description

Eravacycline Impurity 7(TP-498） (CAS CATO-C4X-29387) is a certified pharmaceutical impurity reference standard with the molecular formula C27H31FN4O8 and a molecular weight of 558.56 g/mol.

Based on its molecular formula C27H31FN4O8, Eravacycline Impurity 7(TP-498） contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 558.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Eravacycline Impurity 7(TP-498） 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.
