4-((5-(Thiophen-3-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)methyl)benzene-1,2-diol CAS 858117-52-9 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 4-((5-(Thiophen-3-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)methyl)benzene-1,2-diol.

4-((5-(Thiophen-3-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)methyl)benzene-1,2-diol (CAS 858117-52-9), molecular formula C18H14N2O2S and molecular weight 322.38 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H14N2O2S, 4-((5-(Thiophen-3-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)methyl)benzene-1,2-diol contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 322.38 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.
