2,5-Dimethoxy-N-((tetrahydrofuran-2-yl)methyl)benzenesulfonamide CAS 313403-07-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Dimethoxy-N-((tetrahydrofuran-2-yl)methyl)benzenesulfonamide.

2,5-Dimethoxy-N-((tetrahydrofuran-2-yl)methyl)benzenesulfonamide (CAS 313403-07-5), molecular formula C13H19NO5S and molecular weight 301.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H19NO5S, 2,5-Dimethoxy-N-((tetrahydrofuran-2-yl)methyl)benzenesulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 301.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
