Chemical Structure
Description
The occurrence of Tris(2,2,6,6-tetramethyl-3,5-heptanedione)chromium(III) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tris(2,2,6,6-tetramethyl-3,5-heptanedione)chromium(III) (CAS 14434-47-0), molecular formula C33H57CrO6 and molecular weight 601.80 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Tris(2,2,6,6-tetramethyl-3,5-heptanedione)chromium(III) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 601.80 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
