1-Phenyl-4-{7-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}piperazine CAS 338403-70-6

Description

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.

1-Phenyl-4-{7-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}piperazine (CAS 338403-70-6) is a high-purity analytical reference standard with the molecular formula C21H20N6 and a molecular weight of 356.42 g/mol.

Structurally, 1-Phenyl-4-{7-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}piperazine (C21H20N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 356.42 g/mol, it falls into the moderately-high-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).

As a certified reference material (CRM), 1-Phenyl-4-{7-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}piperazine 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.
