As a certified reference material (CRM), 4,6-Dimethylpyrimidine 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.
4,6-Dimethylpyrimidine (CAS 1558-17-4), molecular formula C6H8N2 and molecular weight 108.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,6-Dimethylpyrimidine (C6H8N2) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 108.14 g/mol, it falls into the low-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).
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.
