Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 311.14 g/mol gives n-Ethyl-4-iodobenzene-1-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
n-Ethyl-4-iodobenzene-1-sulfonamide (CAS 881302-29-0) is a high-purity analytical reference standard with the molecular formula C8H10INO2S and a molecular weight of 311.14 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution, n-Ethyl-4-iodobenzene-1-sulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), n-Ethyl-4-iodobenzene-1-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.
