Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4':2',2'':4'',4'''-Quaterpyridine.
4,4':2',2'':4'',4'''-Quaterpyridine (CAS 125330-07-6), molecular formula C20H14N4 and molecular weight 310.35 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,4':2',2'':4'',4'''-Quaterpyridine (C20H14N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 310.35 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
