Chemical Structure

4,4'-Di-tert-butyl-2-nitro-1,1'-biphenyl CAS 69386-34-1 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.

CATO supplies 4,4'-Di-tert-butyl-2-nitro-1,1'-biphenyl (CAS 69386-34-1), a certified reference material (molecular formula C20H25NO2, MW 311.42 g/mol) for analytical method development and quality control.

Based on its molecular formula C20H25NO2, 4,4'-Di-tert-butyl-2-nitro-1,1'-biphenyl contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
