N',2-bis(4-ethoxyphenyl)hydrazine-1-carbohydrazide CAS 29639-08-5

Description

Compared with other compounds in its class, the molecular weight of 330.38 g/mol gives N',2-bis(4-ethoxyphenyl)hydrazine-1-carbohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N',2-bis(4-ethoxyphenyl)hydrazine-1-carbohydrazide (CAS 29639-08-5), molecular formula C17H22N4O3 and molecular weight 330.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N',2-bis(4-ethoxyphenyl)hydrazine-1-carbohydrazide (C17H22N4O3) is characterized by a steroid core, 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).

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.

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.
