Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(1-oxo-1,3-dihydroisobenzofuran-5-yl)thiophene-2-sulfonamide.
N-(1-oxo-1,3-dihydroisobenzofuran-5-yl)thiophene-2-sulfonamide (CAS 632292-96-7) is a high-purity analytical reference standard with the molecular formula C12H9NO4S2 and a molecular weight of 295.33 g/mol.
The molecular framework of N-(1-oxo-1,3-dihydroisobenzofuran-5-yl)thiophene-2-sulfonamide (C12H9NO4S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
