(4-Chlorophenyl)(1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl)methanol CAS 189089-86-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Chlorophenyl)(1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl)methanol.

CATO supplies (4-Chlorophenyl)(1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl)methanol (CAS 189089-86-9), a certified reference material (molecular formula C20H15ClN2O3S, MW 398.86 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (4-Chlorophenyl)(1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
