2,10-Bis(4-chlorophenyl)-1,2,4,9,10,12-hexaazadispiro[4.2.4^{8}.2^{5}]tetradecane-3,11-dione CAS 338956-29-9

Description

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.

2,10-Bis(4-chlorophenyl)-1,2,4,9,10,12-hexaazadispiro[4.2.4^{8}.2^{5}]tetradecane-3,11-dione (CAS 338956-29-9), molecular formula C20H20Cl2N6O2 and molecular weight 447.32 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 substitution, 2,10-Bis(4-chlorophenyl)-1,2,4,9,10,12-hexaazadispiro[4.2.4^{8}.2^{5}]tetradecane-3,11-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 447.32 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.

As a certified reference material (CRM), 2,10-Bis(4-chlorophenyl)-1,2,4,9,10,12-hexaazadispiro[4.2.4^{8}.2^{5}]tetradecane-3,11-dione 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.
