Chemical Structure

(4-Bromo-2,2,5,5-tetramethyl-2,5-dihydro-1H-pyrrol-3-yl)methanol-1-oxyl CAS 85591-93-1 chemical structure

Description

The occurrence of (4-Bromo-2,2,5,5-tetramethyl-2,5-dihydro-1H-pyrrol-3-yl)methanol-1-oxyl is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4-Bromo-2,2,5,5-tetramethyl-2,5-dihydro-1H-pyrrol-3-yl)methanol-1-oxyl (CAS 85591-93-1) is a high-purity analytical reference standard with the molecular formula C9H16BrNO2 and a molecular weight of 250.13 g/mol.

The molecular framework of (4-Bromo-2,2,5,5-tetramethyl-2,5-dihydro-1H-pyrrol-3-yl)methanol-1-oxyl (C9H16BrNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
