Chemical Structure
Description
As a certified reference material (CRM), Diethyl (3-chloro-6-methyl-4-(p-tolylamino)quinolin-2-yl)phosphonate 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.
CATO supplies Diethyl (3-chloro-6-methyl-4-(p-tolylamino)quinolin-2-yl)phosphonate (CAS 107292-76-2), a certified reference material (molecular formula C21H24ClN2O3P, MW 418.85 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage, chlorine substitution, Diethyl (3-chloro-6-methyl-4-(p-tolylamino)quinolin-2-yl)phosphonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.85 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.
