Chemical Structure

1,2,3,4-Hydroquinoline CAS 635-46-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 133.19 g/mol gives 1,2,3,4-Hydroquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2,3,4-Hydroquinoline (CAS 635-46-1), molecular formula C9H11N and molecular weight 133.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,2,3,4-Hydroquinoline (C9H11N) 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 133.19 g/mol, it falls into the low-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.

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.
