Chemical Structure

Lombazole CAS 60628-98-0 chemical structure

Description

Lombazole (CAS 60628-98-0), molecular formula C22H17ClN2 and molecular weight 344.84 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Lombazole (C22H17ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 344.84 g/mol, it falls into the moderately-high-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.

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.
