Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,6-Dimethoxy-1-methyl-2,3,9,9a-tetrahydro-1H-benzo[de]quinolin-7(8H)-one.
5,6-Dimethoxy-1-methyl-2,3,9,9a-tetrahydro-1H-benzo[de]quinolin-7(8H)-one (CAS 36846-64-7) is a high-purity analytical reference standard with the molecular formula C15H19NO3 and a molecular weight of 261.32 g/mol.
Structurally, 5,6-Dimethoxy-1-methyl-2,3,9,9a-tetrahydro-1H-benzo[de]quinolin-7(8H)-one (C15H19NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 261.32 g/mol, it falls into the medium-molecular-weight range. 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.
