S-(1H-Benzo[d]imidazol-2-yl)-N-ethylthiohydroxylamine CAS 149679-62-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including S-(1H-Benzo[d]imidazol-2-yl)-N-ethylthiohydroxylamine.

S-(1H-Benzo[d]imidazol-2-yl)-N-ethylthiohydroxylamine (CAS 149679-62-9) is a high-purity analytical reference standard with the molecular formula C9H11N3S and a molecular weight of 193.27 g/mol.

Structurally, S-(1H-Benzo[d]imidazol-2-yl)-N-ethylthiohydroxylamine (C9H11N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 193.27 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.
