Description

Compared with other compounds in its class, the molecular weight of 204.66 g/mol gives 5-Chloro-7,8-dihydro-6H-cyclopenta[b][1,8]naphthyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Chloro-7,8-dihydro-6H-cyclopenta[b][1,8]naphthyridine (CAS 267220-21-3), molecular formula C11H9ClN2 and molecular weight 204.66 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-Chloro-7,8-dihydro-6H-cyclopenta[b][1,8]naphthyridine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
