Chemical Structure

5-Ethyl-N-((4-(thiophen-2-yl)tetrahydro-2H-pyran-4-yl)methyl)thiophene-2-sulfonamide CAS 1203111-98-1 chemical structure

Description

5-Ethyl-N-((4-(thiophen-2-yl)tetrahydro-2H-pyran-4-yl)methyl)thiophene-2-sulfonamide (CAS 1203111-98-1) is a high-purity analytical reference standard with the molecular formula C16H21NO3S3 and a molecular weight of 371.54 g/mol.

5-Ethyl-N-((4-(thiophen-2-yl)tetrahydro-2H-pyran-4-yl)methyl)thiophene-2-sulfonamide (C16H21NO3S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. 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.

As a certified reference material (CRM), 5-Ethyl-N-((4-(thiophen-2-yl)tetrahydro-2H-pyran-4-yl)methyl)thiophene-2-sulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
