Description
CATO supplies N'-(5-Chloro-2,6-Difluoropyrimidin-4-ylBenzene-1,3-Diamine (CAS 79817-71-3), a certified reference material (molecular formula C10H7ClF2N4, MW 256.64 g/mol) for analytical method development and quality control.
Structurally, N'-(5-Chloro-2,6-Difluoropyrimidin-4-ylBenzene-1,3-Diamine (C10H7ClF2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 256.64 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), N'-(5-Chloro-2,6-Difluoropyrimidin-4-ylBenzene-1,3-Diamine 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.
