Chemical Structure
Description
As a certified reference material (CRM), 2,4,5,6-Tetrachloropyrimidine 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.
CATO supplies 2,4,5,6-Tetrachloropyrimidine (CAS 1780-40-1), a certified reference material (molecular formula C4Cl4N2, MW 217.87 g/mol) for analytical method development and quality control.
Structurally, 2,4,5,6-Tetrachloropyrimidine (C4Cl4N2) contains a nitrile group, chlorine substitution. 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 217.87 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
