Chemical Structure
Description
As a certified reference material (CRM), 2,6-Bis(trifluoromethyl)pyrimidine-4-carbaldehyde 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.
2,6-Bis(trifluoromethyl)pyrimidine-4-carbaldehyde (CAS 944900-92-9) is a high-purity analytical reference standard with the molecular formula C7H2F6N2O and a molecular weight of 244.09 g/mol.
The molecular framework of 2,6-Bis(trifluoromethyl)pyrimidine-4-carbaldehyde (C7H2F6N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
