4H-Benzo[d]imidazo[1,5-a]imidazole CAS 16151-99-8

Description

Compared with other compounds in its class, the molecular weight of 157.17 g/mol gives 4H-Benzo[d]imidazo[1,5-a]imidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4H-Benzo[d]imidazo[1,5-a]imidazole (CAS 16151-99-8), a certified reference material (molecular formula C9H7N3, MW 157.17 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4H-Benzo[d]imidazo[1,5-a]imidazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 157.17 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).

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.
