Naproxen Nitrile Impurity CAS 67886-70-8 chemical structure

Description

CATO supplies Naproxen Nitrile Impurity (CAS 67886-70-8), a certified reference material (molecular formula C12H9NO, MW 183.21 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H9NO, Naproxen Nitrile Impurity contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 183.21 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Naproxen Nitrile Impurity 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.
