Description
The occurrence of 496-30-0 2H-Indole-2-thione, 1,3-dihydro- (9CI) 2-Indolinethione 5-21-08-00018 (Beilstein Handbook Reference) Benzazoline-2-thione BRN 0002992 1,3-Dihydro-2H-indole-2-thione is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
496-30-0 2H-Indole-2-thione, 1,3-dihydro- (9CI) 2-Indolinethione 5-21-08-00018 (Beilstein Handbook Reference) Benzazoline-2-thione BRN 0002992 1,3-Dihydro-2H-indole-2-thione (CAS 496-30-0), molecular formula C8H7NS and molecular weight 149.21 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H7NS, 496-30-0 2H-Indole-2-thione, 1,3-dihydro- (9CI) 2-Indolinethione 5-21-08-00018 (Beilstein Handbook Reference) Benzazoline-2-thione BRN 0002992 1,3-Dihydro-2H-indole-2-thione contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 149.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
