Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Tosyl-1,2-dihydroquinolin-7-ol.
1-Tosyl-1,2-dihydroquinolin-7-ol (CAS 333383-93-0) is a high-purity analytical reference standard with the molecular formula C16H15NO3S and a molecular weight of 301.36 g/mol.
Structurally, 1-Tosyl-1,2-dihydroquinolin-7-ol (C16H15NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 301.36 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.
