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.

CATO supplies 2-amino-2-(phenylhydrazinylidene)acetic acid ethyl ester 36999-43-6 A823497 ethyl 2-azanyl-2-(phenylhydrazinylidene)ethanoate (CAS 36999-43-6), a certified reference material (molecular formula C10H13N3O2, MW 207.23 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-amino-2-(phenylhydrazinylidene)acetic acid ethyl ester 36999-43-6 A823497 ethyl 2-azanyl-2-(phenylhydrazinylidene)ethanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
