Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2,6,6-Tetramethylpiperidine-d18-1-oxyl.
2,2,6,6-Tetramethylpiperidine-d18-1-oxyl (CAS 205679-68-1) is a high-purity analytical reference standard with the molecular formula C9D18NO and a molecular weight of 174.36 g/mol.
Structurally, 2,2,6,6-Tetramethylpiperidine-d18-1-oxyl (C9D18NO) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.5, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 174.36 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
