Chemical Structure
Description
The molecular framework of 1-Oxo-2,3,4,9-tetrahydro-1H-carbazole-6-carboxylic acid (C13H11NO3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1-Oxo-2,3,4,9-tetrahydro-1H-carbazole-6-carboxylic acid (CAS 104904-59-8) is a high-purity analytical reference standard with the molecular formula C13H11NO3 and a molecular weight of 229.23 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-Oxo-2,3,4,9-tetrahydro-1H-carbazole-6-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
