N',2-di-p-tolylhydrazine-1-carbohydrazide CAS 57249-12-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

N',2-di-p-tolylhydrazine-1-carbohydrazide (CAS 57249-12-4), molecular formula C15H18N4O and molecular weight 270.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N',2-di-p-tolylhydrazine-1-carbohydrazide (C15H18N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).

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.
