Chemical Structure
Description
As a certified reference material (CRM), (+/-)-naproxen-(methoxy-d3) 958293-79-3 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.
(+/-)-naproxen-(methoxy-d3) 958293-79-3 (CAS 958293-79-3) is a high-purity analytical reference standard with the molecular formula C14H21D3O3 and a molecular weight of 243.36 g/mol.
The molecular framework of (+/-)-naproxen-(methoxy-d3) 958293-79-3 (C14H21D3O3) is characterized by deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
