Chemical Structure

1,3-Dimethyl-9H-carbazole CAS 18992-68-2 chemical structure

Description

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.

1,3-Dimethyl-9H-carbazole (CAS 18992-68-2) is a high-purity analytical reference standard with the molecular formula C14H13N and a molecular weight of 195.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1,3-Dimethyl-9H-carbazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 195.26 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.
