2-(4-(2-Fluoro-5-(3-(6-methylpyridin-2-yl)-1H-pyrazol-4-yl)phenyl)-1H-pyrazol-1-yl)ethan-1-ol CAS 879487-87-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-(2-Fluoro-5-(3-(6-methylpyridin-2-yl)-1H-pyrazol-4-yl)phenyl)-1H-pyrazol-1-yl)ethan-1-ol.

2-(4-(2-Fluoro-5-(3-(6-methylpyridin-2-yl)-1H-pyrazol-4-yl)phenyl)-1H-pyrazol-1-yl)ethan-1-ol (CAS 879487-87-3) is a high-purity analytical reference standard with the molecular formula C20H18FN5O and a molecular weight of 363.39 g/mol.

Structurally, 2-(4-(2-Fluoro-5-(3-(6-methylpyridin-2-yl)-1H-pyrazol-4-yl)phenyl)-1H-pyrazol-1-yl)ethan-1-ol (C20H18FN5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 363.39 g/mol, it falls into the moderately-high-molecular-weight range. 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.
