Description
Compared with other compounds in its class, the molecular weight of 271.70 g/mol gives Bromfenac Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bromfenac Impurity 22 (CAS 61112-01-4) is a certified pharmaceutical impurity reference standard with the molecular formula C15H10ClNO2 and a molecular weight of 271.70 g/mol.
Structurally, Bromfenac Impurity 22 (C15H10ClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 271.70 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Bromfenac Impurity 22 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.
