Description
As a certified reference material (CRM), Loxoprofen Impurity 48 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Loxoprofen Impurity 48 (CAS 80530-54-7), a pharmacopoeial impurity reference standard (molecular formula C11H13ClO2, MW 212.67 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C11H13ClO2, Loxoprofen Impurity 48 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
