Chemical Structure

Nabumetone impurity 31 CAS CATO-C4X-284831 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 242.27 g/mol gives Nabumetone impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Nabumetone impurity 31 (CAS CATO-C4X-284831), a pharmacopoeial impurity reference standard (molecular formula C15H14O3, MW 242.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C15H14O3, Nabumetone impurity 31 contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Nabumetone impurity 31 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.
