Compared with other compounds in its class, the molecular weight of 288.75 g/mol gives Linezolid Impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Linezolid Impurity 29 (CAS 1610690-08-8) is a certified pharmaceutical impurity reference standard with the molecular formula C13H18ClFN2O2 and a molecular weight of 288.75 g/mol.
Structurally, Linezolid Impurity 29 (C13H18ClFN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 288.75 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Linezolid Impurity 29 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.
