Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((2-(2,2,6,6-Tetramethylpiperidin-1-yl)ethyl)thio)quinazolin-4(1H)-one.
2-((2-(2,2,6,6-Tetramethylpiperidin-1-yl)ethyl)thio)quinazolin-4(1H)-one (CAS 684276-18-4) is a high-purity analytical reference standard with the molecular formula C19H27N3OS and a molecular weight of 345.50 g/mol.
Structurally, 2-((2-(2,2,6,6-Tetramethylpiperidin-1-yl)ethyl)thio)quinazolin-4(1H)-one (C19H27N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 345.50 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
