Chemical Structure
Description
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.
N-[(2,6-Dichlorobenzyl)oxy]-N-[(hydroxyimino)methyl]urea (CAS 338403-98-8), molecular formula C9H9Cl2N3O3 and molecular weight 278.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-[(2,6-Dichlorobenzyl)oxy]-N-[(hydroxyimino)methyl]urea (C9H9Cl2N3O3) 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 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.
