Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 501.40 g/mol gives Carprofen Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Carprofen Impurity 2 (CAS CATO-C4X-30342) is a certified pharmaceutical impurity reference standard with the molecular formula C29H22Cl2N2O2 and a molecular weight of 501.40 g/mol.
Structurally, Carprofen Impurity 2 (C29H22Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 501.40 g/mol, it falls into the moderately-high-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).
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 Carprofen Impurity 2 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.
