Chemical Structure
Description
As a certified reference material (CRM), Naphthalen-2-yl 6-bromo-2-(4-chlorophenyl)quinoline-4-carboxylate 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.
Naphthalen-2-yl 6-bromo-2-(4-chlorophenyl)quinoline-4-carboxylate (CAS 355421-76-0), molecular formula C26H15BrClNO2 and molecular weight 488.76 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, Naphthalen-2-yl 6-bromo-2-(4-chlorophenyl)quinoline-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 488.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
