Chemical Structure

Quinoline CAS 91-22-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 129.16 g/mol gives Quinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Quinoline (CAS 91-22-5) is a high-purity analytical reference standard with the molecular formula C9H7N and a molecular weight of 129.16 g/mol.

Structurally, Quinoline (C9H7N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 129.16 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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

CATO manufactures Quinoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
