Chemical Structure
Description
The occurrence of Flurbiprofen-d3 is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Flurbiprofen-d3 (CAS 1185133-81-6) is a high-purity analytical reference standard with the molecular formula C15H10D3FO2 and a molecular weight of 247.28 g/mol.
Based on its molecular formula C15H10D3FO2, Flurbiprofen-d3 contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Flurbiprofen-d3 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.
