Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 37566-53-3 4-(Ethoxyfluorophosphinyloxy)-2,2,6,6-tetramethyl-1-piperidinyloxy, free radical 4-(Ethoxyfluorophosphinyloxy)-TEMPO 4-Ethoxyfluorophosphinyloxy TEMPO 4-[(Ethoxyflorophosphinyl)oxy]-2,2,6,6,-tetramethyl-1-piperidine-1-oxyl4-Hydroxy-2,2,6,6-tetramethylpiperidino-1-oxyl monoethyl phosphorofluoridate ester.

CATO supplies 37566-53-3 4-(Ethoxyfluorophosphinyloxy)-2,2,6,6-tetramethyl-1-piperidinyloxy, free radical 4-(Ethoxyfluorophosphinyloxy)-TEMPO 4-Ethoxyfluorophosphinyloxy TEMPO 4-[(Ethoxyflorophosphinyl)oxy]-2,2,6,6,-tetramethyl-1-piperidine-1-oxyl4-Hydroxy-2,2,6,6-tetramethylpiperidino-1-oxyl monoethyl phosphorofluoridate ester (CAS 37566-53-3), a certified reference material (molecular formula C11H22FNO4P, MW 282.27 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H22FNO4P, 37566-53-3 4-(Ethoxyfluorophosphinyloxy)-2,2,6,6-tetramethyl-1-piperidinyloxy, free radical 4-(Ethoxyfluorophosphinyloxy)-TEMPO 4-Ethoxyfluorophosphinyloxy TEMPO 4-[(Ethoxyflorophosphinyl)oxy]-2,2,6,6,-tetramethyl-1-piperidine-1-oxyl4-Hydroxy-2,2,6,6-tetramethylpiperidino-1-oxyl monoethyl phosphorofluoridate ester contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 282.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
