Chemical Structure

4-(o-Tolyl)cinnoline CAS 90141-96-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 220.27 g/mol gives 4-(o-Tolyl)cinnoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(o-Tolyl)cinnoline (CAS 90141-96-1), molecular formula C15H12N2 and molecular weight 220.27 g/mol, is a CATO reference standard with documented purity and traceability.

4-(o-Tolyl)cinnoline (C15H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 4-(o-Tolyl)cinnoline 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.
