Chemical Structure
Description
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 939791-38-5 FK2M84H8UI PF-00562271 Methanesulfonamide, N-(3-(((2-((2,3-dihydro-2-oxo-1H-indol-5-yl)amino)-5- (trifluoromethyl)-4-pyrimidinyl)amino)methyl)-2-pyridinyl)-N-methyl-, benzenesulfonate (1:1) PF-562271 PF-562,271 UNII-FK2M84H8UI PF 562271 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 665.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
939791-38-5 FK2M84H8UI PF-00562271 Methanesulfonamide, N-(3-(((2-((2,3-dihydro-2-oxo-1H-indol-5-yl)amino)-5- (trifluoromethyl)-4-pyrimidinyl)amino)methyl)-2-pyridinyl)-N-methyl-, benzenesulfonate (1:1) PF-562271 PF-562,271 UNII-FK2M84H8UI PF 562271 (CAS 939791-38-5) is a high-purity analytical reference standard with the molecular formula C21H20F3N7O3SC6H6O3S and a molecular weight of 665.66 g/mol.
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), 939791-38-5 FK2M84H8UI PF-00562271 Methanesulfonamide, N-(3-(((2-((2,3-dihydro-2-oxo-1H-indol-5-yl)amino)-5- (trifluoromethyl)-4-pyrimidinyl)amino)methyl)-2-pyridinyl)-N-methyl-, benzenesulfonate (1:1) PF-562271 PF-562,271 UNII-FK2M84H8UI PF 562271 meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
