Chemical Structure
Description
7-Methoxy-3-methyl-5-tosyl-2,3,4,5-tetrahydro-1H-phospholo[2,3-c]quinoline 3-oxide (CAS 84779-95-3), molecular formula C20H22NO4PS and molecular weight 403.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Methoxy-3-methyl-5-tosyl-2,3,4,5-tetrahydro-1H-phospholo[2,3-c]quinoline 3-oxide (C20H22NO4PS) contains a flavonoid core, an amide group, a sulfone group, a phosphate ester 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 403.43 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
