Description
As a certified reference material (CRM), Heptyl 6-chloro-2-(p-tolyl)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.
Heptyl 6-chloro-2-(p-tolyl)quinoline-4-carboxylate (CAS 355421-12-4) is a high-purity analytical reference standard with the molecular formula C24H26ClNO2 and a molecular weight of 395.92 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Heptyl 6-chloro-2-(p-tolyl)quinoline-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 395.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
