Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(2,4-Dinitrophenyl)cyclohexanone N-phenylhydrazone (CAS 672949-60-9), molecular formula C18H18N4O4 and molecular weight 354.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(2,4-Dinitrophenyl)cyclohexanone N-phenylhydrazone (C18H18N4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 354.36 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
