Chemical Structure
Description
3,6-Di-tert-butyl-9-(4-vinylphenyl)-9H-carbazole (CAS 2229755-23-9), molecular formula C28H31N and molecular weight 381.55 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C28H31N, 3,6-Di-tert-butyl-9-(4-vinylphenyl)-9H-carbazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 381.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 3,6-Di-tert-butyl-9-(4-vinylphenyl)-9H-carbazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
