Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 11H-Indeno[1,2-b]quinoline.
CATO supplies 11H-Indeno[1,2-b]quinoline (CAS 243-51-6), a certified reference material (molecular formula C16H11N, MW 217.27 g/mol) for analytical method development and quality control.
The molecular framework of 11H-Indeno[1,2-b]quinoline (C16H11N) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 11H-Indeno[1,2-b]quinoline 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.
