Roxithromycin Impurity A CAS 59319-72-1

Description

The occurrence of Roxithromycin Impurity A is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Roxithromycin Impurity A (CAS 59319-72-1) is a high-purity analytical reference standard with the molecular formula C37H67NO13H2O and a molecular weight of 751.95 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Roxithromycin Impurity A is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 751.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Roxithromycin Impurity A 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.
