The occurrence of Cyclopenta[b]thiazolo[4,5-e]indole 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.
Cyclopenta[b]thiazolo[4,5-e]indole (CAS 19563-68-9) is a high-purity analytical reference standard with the molecular formula C12H6N2S and a molecular weight of 210.25 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, Cyclopenta[b]thiazolo[4,5-e]indole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 210.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
