Description

The occurrence of 2-Ethoxy-N-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzamide 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.

2-Ethoxy-N-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzamide (CAS 899745-44-9) is a high-purity analytical reference standard with the molecular formula C18H17N3O3 and a molecular weight of 323.35 g/mol.

Structurally, 2-Ethoxy-N-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzamide (C18H17N3O3) 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 323.35 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.

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.
