Chemical Structure

N-(Dihydrofuran-2(3H)-ylidene)-4-methylbenzenesulfonamide CAS 1209-75-2 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-(Dihydrofuran-2(3H)-ylidene)-4-methylbenzenesulfonamide.

N-(Dihydrofuran-2(3H)-ylidene)-4-methylbenzenesulfonamide (CAS 1209-75-2) is a high-purity analytical reference standard with the molecular formula C11H13NO3S and a molecular weight of 239.29 g/mol.

N-(Dihydrofuran-2(3H)-ylidene)-4-methylbenzenesulfonamide (C11H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures N-(Dihydrofuran-2(3H)-ylidene)-4-methylbenzenesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
