Chemical Structure
Description
5-[M-(Chlorodifluoromethoxy)Benzyl]-2,4-Pyrimidinediamine (C12H11ClF2N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-[M-(Chlorodifluoromethoxy)Benzyl]-2,4-Pyrimidinediamine (CAS 50824-01-6) is a high-purity analytical reference standard with the molecular formula C12H11ClF2N4O and a molecular weight of 300.69 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
