The molecular framework of 728-40-5 2,6-Di-tert-butyl-4-nitrophenol Phenol, 2,6-bis(1,1-dimethylethyl)-4-nitro- (9CI) Phenol, 2,6-di-tert-butyl-4-nitro- Phenol, 2,6-bis(1,1-dimethylethyl)-4-nitro- 4-06-00-03493 (Beilstein Handbook Reference) AI3-25569 BAY 28589 Bayer 28589 Bayer 4889 2,6-Bis(1,1-dimethylethyl)-4-nitrophenol BRN 2056124 ENT 25,569 NSC 81682 (C14H27NO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 728-40-5 2,6-Di-tert-butyl-4-nitrophenol Phenol, 2,6-bis(1,1-dimethylethyl)-4-nitro- (9CI) Phenol, 2,6-di-tert-butyl-4-nitro- Phenol, 2,6-bis(1,1-dimethylethyl)-4-nitro- 4-06-00-03493 (Beilstein Handbook Reference) AI3-25569 BAY 28589 Bayer 28589 Bayer 4889 2,6-Bis(1,1-dimethylethyl)-4-nitrophenol BRN 2056124 ENT 25,569 NSC 81682 meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
