Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Chloro-2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-5-fluoro-6-methylpyrimidine (CAS 1823182-26-8), molecular formula C11H5Cl2F4N3 and molecular weight 326.08 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H5Cl2F4N3, 4-Chloro-2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-5-fluoro-6-methylpyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 326.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
