Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 212.72 g/mol gives 2-chloro-5-n-heptylpyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-chloro-5-n-heptylpyrimidine (CAS 221641-56-1) is a high-purity analytical reference standard with the molecular formula C11H17ClN2 and a molecular weight of 212.72 g/mol.
2-chloro-5-n-heptylpyrimidine (C11H17ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
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.
