Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Ethoxy-N-((tetrahydrofuran-2-yl)methyl)naphthalene-1-sulfonamide.
4-Ethoxy-N-((tetrahydrofuran-2-yl)methyl)naphthalene-1-sulfonamide (CAS 447410-62-0) is a high-purity analytical reference standard with the molecular formula C17H21NO4S and a molecular weight of 335.42 g/mol.
Structurally, 4-Ethoxy-N-((tetrahydrofuran-2-yl)methyl)naphthalene-1-sulfonamide (C17H21NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 335.42 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.
