Description

5-Hydroxy-2,2,6,6-tetramethyl-4-((R)-2-methyl-1-(2,4,6-trihydroxy-3-((R)-1-(2-hydroxy-3,3,5,5-tetramethyl-4,6-dioxocyclohex-1-en-1-yl)-2-methylpropyl)-5-isobutyrylphenyl)propyl)cyclohex-4-ene-1,3-dione (CAS 54247-21-1), molecular formula C38H52O10 and molecular weight 668.81 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 5-Hydroxy-2,2,6,6-tetramethyl-4-((R)-2-methyl-1-(2,4,6-trihydroxy-3-((R)-1-(2-hydroxy-3,3,5,5-tetramethyl-4,6-dioxocyclohex-1-en-1-yl)-2-methylpropyl)-5-isobutyrylphenyl)propyl)cyclohex-4-ene-1,3-dione is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 668.81 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).

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), 5-Hydroxy-2,2,6,6-tetramethyl-4-((R)-2-methyl-1-(2,4,6-trihydroxy-3-((R)-1-(2-hydroxy-3,3,5,5-tetramethyl-4,6-dioxocyclohex-1-en-1-yl)-2-methylpropyl)-5-isobutyrylphenyl)propyl)cyclohex-4-ene-1,3-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.
