Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 264.14 g/mol gives N-(4-bromophenyl)-N-methylmethanesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-(4-bromophenyl)-N-methylmethanesulfonamide (CAS 99980-38-8) is a high-purity analytical reference standard with the molecular formula C8H10BrNO2S and a molecular weight of 264.14 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, N-(4-bromophenyl)-N-methylmethanesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(4-bromophenyl)-N-methylmethanesulfonamide 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.
