Chemical Structure

2H-Cyclopenta[b]quinoxaline CAS 774-68-5 chemical structure

Description

The occurrence of 2H-Cyclopenta[b]quinoxaline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2H-Cyclopenta[b]quinoxaline (CAS 774-68-5), molecular formula C11H8N2 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2H-Cyclopenta[b]quinoxaline (C11H8N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 168.19 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.

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

As a certified reference material (CRM), 2H-Cyclopenta[b]quinoxaline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
