Chemical Structure

3-cyclopropanecarbonyl-4H,5H,6H-cyclopenta[b]thiophen-2-amine CAS 1797654-98-8 chemical structure

Description

The occurrence of 3-cyclopropanecarbonyl-4H,5H,6H-cyclopenta[b]thiophen-2-amine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-cyclopropanecarbonyl-4H,5H,6H-cyclopenta[b]thiophen-2-amine (CAS 1797654-98-8), a certified reference material (molecular formula C11H13NOS, MW 207.29 g/mol) for analytical method development and quality control.

Structurally, 3-cyclopropanecarbonyl-4H,5H,6H-cyclopenta[b]thiophen-2-amine (C11H13NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 207.29 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
