CATO supplies Tert-butyl 2-bromo-6,6-dimethyl-4-oxo-4,6-dihydro-5H-thieno[2,3-c]pyrrole-5-carboxylate (CAS 1951483-78-5), a certified reference material (molecular formula C13H16BrNO3S, MW 346.24 g/mol) for analytical method development and quality control.
The molecular framework of Tert-butyl 2-bromo-6,6-dimethyl-4-oxo-4,6-dihydro-5H-thieno[2,3-c]pyrrole-5-carboxylate (C13H16BrNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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.
