As a certified reference material (CRM), 1,2,3,4-Tetramethyl-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.
CATO supplies 1,2,3,4-Tetramethyl-9H-carbazole (CAS 33553-27-4), a certified reference material (molecular formula C16H17N, MW 223.31 g/mol) for analytical method development and quality control.
The molecular framework of 1,2,3,4-Tetramethyl-9H-carbazole (C16H17N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
