Loxoprofen impurity 100 CAS CATO-C4X-1488100

Description

Compared with other compounds in its class, the molecular weight of 336.02 g/mol gives Loxoprofen impurity 100 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Loxoprofen impurity 100 (CAS CATO-C4X-1488100) is a certified pharmaceutical impurity reference standard with the molecular formula C11H12Br2O2 and a molecular weight of 336.02 g/mol.

Structurally, Loxoprofen impurity 100 (C11H12Br2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 336.02 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Loxoprofen impurity 100 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.
