(3aS,8aS)-4,4,8,8-Tetrakis(3,5-dimethylphenyl)tetrahydro-2,2-dimethyl-6-phenyl-1,3-dioxolo[4,5-e][1,3,2]dioxaphosphepin CAS 1169835-86-2

Description

(3aS,8aS)-4,4,8,8-Tetrakis(3,5-dimethylphenyl)tetrahydro-2,2-dimethyl-6-phenyl-1,3-dioxolo[4,5-e][1,3,2]dioxaphosphepin (CAS 1169835-86-2), molecular formula C45H49O4P and molecular weight 684.84 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (3aS,8aS)-4,4,8,8-Tetrakis(3,5-dimethylphenyl)tetrahydro-2,2-dimethyl-6-phenyl-1,3-dioxolo[4,5-e][1,3,2]dioxaphosphepin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 684.84 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), (3aS,8aS)-4,4,8,8-Tetrakis(3,5-dimethylphenyl)tetrahydro-2,2-dimethyl-6-phenyl-1,3-dioxolo[4,5-e][1,3,2]dioxaphosphepin 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.
