2-(3-Hydroxy-3H-indol-2-yl)hydrazinecarboxamide CAS 63244-99-5

Description

The occurrence of 2-(3-Hydroxy-3H-indol-2-yl)hydrazinecarboxamide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3-Hydroxy-3H-indol-2-yl)hydrazinecarboxamide (CAS 63244-99-5), molecular formula C9H10N4O2 and molecular weight 206.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(3-Hydroxy-3H-indol-2-yl)hydrazinecarboxamide (C9H10N4O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 206.20 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
