Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((3-(2,5-Dichlorophenyl)-1,2,4-oxadiazol-5-yl)methoxy)benzaldehyde.
2-((3-(2,5-Dichlorophenyl)-1,2,4-oxadiazol-5-yl)methoxy)benzaldehyde (CAS 1707609-21-9), molecular formula C16H10Cl2N2O3 and molecular weight 349.17 g/mol, is a CATO reference standard with documented purity and traceability.
2-((3-(2,5-Dichlorophenyl)-1,2,4-oxadiazol-5-yl)methoxy)benzaldehyde (C16H10Cl2N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
