Chemical Structure
Description
The molecular framework of tert-butyl 3-bromo-5-phenyl-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (C18H17BrN2O2) is characterized by a steroid core, an amide 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
tert-butyl 3-bromo-5-phenyl-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (CAS 890842-71-4) is a high-purity analytical reference standard with the molecular formula C18H17BrN2O2 and a molecular weight of 373.24 g/mol.
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.
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.
