Description
Compared with other compounds in its class, the molecular weight of 452.48 g/mol gives Linezolid Impurity 94 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Linezolid Impurity 94 (CAS CATO-C4X-107394) is a certified pharmaceutical impurity reference standard with the molecular formula C21H29FN4O6 and a molecular weight of 452.48 g/mol.
Structurally, Linezolid Impurity 94 (C21H29FN4O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 452.48 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Linezolid Impurity 94 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.
