(Z)-3-{[4-(4-chlorophenyl)-1H-pyrazol-5-yl]amino}-2-[(4-methylphenyl)sulfonyl]-2-propenenitrile CAS 1029989-13-6

Description

(Z)-3-{[4-(4-chlorophenyl)-1H-pyrazol-5-yl]amino}-2-[(4-methylphenyl)sulfonyl]-2-propenenitrile (CAS 1029989-13-6), molecular formula C19H15ClN4O2S and molecular weight 398.87 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (Z)-3-{[4-(4-chlorophenyl)-1H-pyrazol-5-yl]amino}-2-[(4-methylphenyl)sulfonyl]-2-propenenitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.87 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.
