2-methyl-4H,5H,6H-cyclopenta[b]thiophen-4-amine CAS 1513420-35-3

Description

The occurrence of 2-methyl-4H,5H,6H-cyclopenta[b]thiophen-4-amine 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.

2-methyl-4H,5H,6H-cyclopenta[b]thiophen-4-amine (CAS 1513420-35-3), molecular formula C8H11NS and molecular weight 153.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-methyl-4H,5H,6H-cyclopenta[b]thiophen-4-amine (C8H11NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 153.24 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).

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.
