106664-95-3 2-Hydroxy-3-[2-(2-hydroxy-3,4-dioxocyclohexa-1,5-dien-1-yl)hydrazinyl]-5-nitrobenzene-1-sulfonic acid DTXSID10552823 CAS 106664-95-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 371.28 g/mol gives 106664-95-3 2-Hydroxy-3-[2-(2-hydroxy-3,4-dioxocyclohexa-1,5-dien-1-yl)hydrazinyl]-5-nitrobenzene-1-sulfonic acid DTXSID10552823 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

106664-95-3 2-Hydroxy-3-[2-(2-hydroxy-3,4-dioxocyclohexa-1,5-dien-1-yl)hydrazinyl]-5-nitrobenzene-1-sulfonic acid DTXSID10552823 (CAS 106664-95-3) is a high-purity analytical reference standard with the molecular formula C12H9N3O9S and a molecular weight of 371.28 g/mol.

Structurally, 106664-95-3 2-Hydroxy-3-[2-(2-hydroxy-3,4-dioxocyclohexa-1,5-dien-1-yl)hydrazinyl]-5-nitrobenzene-1-sulfonic acid DTXSID10552823 (C12H9N3O9S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 371.28 g/mol, it falls into the moderately-high-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.
