n-{1-[4-(1h-pyrazol-1-yl)phenyl]ethylidene}hydroxylamine CAS 1019079-11-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-{1-[4-(1h-pyrazol-1-yl)phenyl]ethylidene}hydroxylamine.

n-{1-[4-(1h-pyrazol-1-yl)phenyl]ethylidene}hydroxylamine (CAS 1019079-11-8) is a high-purity analytical reference standard with the molecular formula C11H11N3O and a molecular weight of 201.22 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, n-{1-[4-(1h-pyrazol-1-yl)phenyl]ethylidene}hydroxylamine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 201.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
