Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-piperazin-1-ylpyrimidine dihydrochloride.
CATO supplies 4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-piperazin-1-ylpyrimidine dihydrochloride (CAS 1177092-99-7), a certified reference material (molecular formula C12H16N6OHCl, MW 296.76 g/mol) for analytical method development and quality control.
4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-piperazin-1-ylpyrimidine dihydrochloride (C12H16N6OHCl) 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. 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.
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.
