Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
9-Methyl-6,7,8,9-tetrahydro-5H-carbazole-3-carboxylic acid (CAS 107455-70-9), molecular formula C14H15NO2 and molecular weight 229.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9-Methyl-6,7,8,9-tetrahydro-5H-carbazole-3-carboxylic acid (C14H15NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 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).
As a certified reference material (CRM), 9-Methyl-6,7,8,9-tetrahydro-5H-carbazole-3-carboxylic acid 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.
