1-Methylbenzo[g]pyridazino[1,2-b]phthalazine-6,13(1H,4H)-dione CAS 67749-18-2

Description

The occurrence of 1-Methylbenzo[g]pyridazino[1,2-b]phthalazine-6,13(1H,4H)-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Methylbenzo[g]pyridazino[1,2-b]phthalazine-6,13(1H,4H)-dione (CAS 67749-18-2), a certified reference material (molecular formula C17H14N2O2, MW 278.31 g/mol) for analytical method development and quality control.

Structurally, 1-Methylbenzo[g]pyridazino[1,2-b]phthalazine-6,13(1H,4H)-dione (C17H14N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 278.31 g/mol, it falls into the medium-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.
