Chemical Structure

N-Butyl-N-phenylbenzenesulfonamide CAS 74805-35-9 chemical structure

Description

As a certified reference material (CRM), N-Butyl-N-phenylbenzenesulfonamide 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.

N-Butyl-N-phenylbenzenesulfonamide (CAS 74805-35-9) is a high-purity analytical reference standard with the molecular formula C16H19NO2S and a molecular weight of 289.39 g/mol.

Structurally, N-Butyl-N-phenylbenzenesulfonamide (C16H19NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 289.39 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
