Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Pyrimidin-2-yl)-1,4-diazepane.
1-(Pyrimidin-2-yl)-1,4-diazepane (CAS 21279-57-2) is a high-purity analytical reference standard with the molecular formula C9H14N4 and a molecular weight of 178.23 g/mol.
Structurally, 1-(Pyrimidin-2-yl)-1,4-diazepane (C9H14N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 178.23 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(Pyrimidin-2-yl)-1,4-diazepane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
