Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 330.74 g/mol gives Furosemide Impurity 55 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Furosemide Impurity 55 (CAS CATO-C4X-140255) is a certified pharmaceutical impurity reference standard with the molecular formula C12H11ClN2O5S and a molecular weight of 330.74 g/mol.
Structurally, Furosemide Impurity 55 (C12H11ClN2O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 330.74 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 Furosemide Impurity 55 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.
