Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-{[1,1'-biphenyl]-4-yl}-3-(3-chlorophenyl)pyrazolo[1,5-a]pyrimidine.
7-{[1,1'-biphenyl]-4-yl}-3-(3-chlorophenyl)pyrazolo[1,5-a]pyrimidine (CAS 685109-53-9) is a high-purity analytical reference standard with the molecular formula C24H16ClN3 and a molecular weight of 381.86 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 7-{[1,1'-biphenyl]-4-yl}-3-(3-chlorophenyl)pyrazolo[1,5-a]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.86 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.
