Eravacycline Impurity 2(TP-2905） CAS CATO-C4X-29382 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 Eravacycline Impurity 2(TP-2905）.

CATO supplies Eravacycline Impurity 2(TP-2905） (CAS CATO-C4X-29382), a pharmacopoeial impurity reference standard (molecular formula C27H31FN4O9, MW 574.55 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Eravacycline Impurity 2(TP-2905） is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 574.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
