9-Methyl-7,8,9,10-tetrahydropyrido[2',3':4,5]thieno[2,3-b][1,6]naphthyridine-2,4-diol (CAS 290299-91-1), molecular formula C14H13N3O2S and molecular weight 287.34 g/mol, is a CATO reference standard with documented purity and traceability.

9-Methyl-7,8,9,10-tetrahydropyrido[2',3':4,5]thieno[2,3-b][1,6]naphthyridine-2,4-diol (C14H13N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
