Description
As a certified reference material (CRM), 1,2,3,4-Tetrahydrobenzo[h]quinoline-3,7-diol 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.
1,2,3,4-Tetrahydrobenzo[h]quinoline-3,7-diol (CAS 5855-89-0) is a high-purity analytical reference standard with the molecular formula C13H13NO2 and a molecular weight of 215.25 g/mol.
The molecular framework of 1,2,3,4-Tetrahydrobenzo[h]quinoline-3,7-diol (C13H13NO2) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
