4,4,6,8-TEtramethyl-2,3-dihydro-1H-quinoline CAS 1700361-55-2

Description

Compared with other compounds in its class, the molecular weight of 189.30 g/mol gives 4,4,6,8-TEtramethyl-2,3-dihydro-1H-quinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4,6,8-TEtramethyl-2,3-dihydro-1H-quinoline (CAS 1700361-55-2), molecular formula C13H19N and molecular weight 189.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,4,6,8-TEtramethyl-2,3-dihydro-1H-quinoline (C13H19N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 189.30 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.

As a certified reference material (CRM), 4,4,6,8-TEtramethyl-2,3-dihydro-1H-quinoline 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.
