Chemical Structure
Description
2-[5-(piperidin-2-yl)-1,2,4-oxadiazol-3-yl]pyrimidine (CAS 1154008-12-4), molecular formula C11H13N5OHCl and molecular weight 267.72 g/mol, is a CATO reference standard with documented purity and traceability.
2-[5-(piperidin-2-yl)-1,2,4-oxadiazol-3-yl]pyrimidine (C11H13N5OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
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.
