Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, Copper bis(2,2,6,6-tetramethyl-3,5-heptanedioneate) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 430.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Copper bis(2,2,6,6-tetramethyl-3,5-heptanedioneate) (CAS 14040-05-2), molecular formula C22H38CuO4 and molecular weight 430.08 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), Copper bis(2,2,6,6-tetramethyl-3,5-heptanedioneate) 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.
