3,3-Dimethylindoline-2-thione CAS 19155-25-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,3-Dimethylindoline-2-thione (CAS 19155-25-0) is a high-purity analytical reference standard with the molecular formula C10H11NS and a molecular weight of 177.27 g/mol.

Structurally, 3,3-Dimethylindoline-2-thione (C10H11NS) 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 177.27 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
