Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (E)-3-nitrobenzaldehyde O-((3,4-dichlorophenyl)carbamoyl) oxime (CAS 39089-88-8), a certified reference material (molecular formula C14H9Cl2N3O4, MW 354.14 g/mol) for analytical method development and quality control.
The molecular framework of (E)-3-nitrobenzaldehyde O-((3,4-dichlorophenyl)carbamoyl) oxime (C14H9Cl2N3O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
