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.
4-Amino-5-chloro-N',N'-diethyl-2-methoxybenzohydrazide hydrochloride (CAS 1415719-66-2), molecular formula C12H18ClN3O2HCl and molecular weight 308.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Amino-5-chloro-N',N'-diethyl-2-methoxybenzohydrazide hydrochloride (C12H18ClN3O2HCl) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
