2-Ethyl-5,8-dihydroquinoxaline CAS 65129-01-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Ethyl-5,8-dihydroquinoxaline.

2-Ethyl-5,8-dihydroquinoxaline (CAS 65129-01-3), molecular formula C10H12N2 and molecular weight 160.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Ethyl-5,8-dihydroquinoxaline (C10H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 160.22 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 2-Ethyl-5,8-dihydroquinoxaline 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.
