Chemical Structure

N-tert-Butyl-4-formylbiphenyl-2-sulfonamide CAS 851902-28-8 chemical structure

Description

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

N-tert-Butyl-4-formylbiphenyl-2-sulfonamide (CAS 851902-28-8) is a high-purity analytical reference standard with the molecular formula C17H19NO3S and a molecular weight of 317.40 g/mol.

Based on its molecular formula C17H19NO3S, N-tert-Butyl-4-formylbiphenyl-2-sulfonamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 317.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
