Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tert-butyl 5-bromo-3-isopropyl-1H-pyrrolo[3,2-b]pyridine-1-carboxylate.
Tert-butyl 5-bromo-3-isopropyl-1H-pyrrolo[3,2-b]pyridine-1-carboxylate (CAS 2351275-18-6), molecular formula C15H19BrN2O2 and molecular weight 339.23 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H19BrN2O2, Tert-butyl 5-bromo-3-isopropyl-1H-pyrrolo[3,2-b]pyridine-1-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 339.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
