Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 195.26 g/mol gives 3,4-Dimethyl-9H-carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,4-Dimethyl-9H-carbazole (CAS 18992-72-8), a certified reference material (molecular formula C14H13N, MW 195.26 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3,4-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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
