Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-{4-[4-(propan-2-yloxy)phenyl]butan-2-ylidene}hydroxylamine.
n-{4-[4-(propan-2-yloxy)phenyl]butan-2-ylidene}hydroxylamine (CAS 1017040-19-5) is a high-purity analytical reference standard with the molecular formula C13H19NO2 and a molecular weight of 221.30 g/mol.
n-{4-[4-(propan-2-yloxy)phenyl]butan-2-ylidene}hydroxylamine (C13H19NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
