Description

The occurrence of (S)-(-)-7,7 inverted exclamation marka-Bis[di(3,5-dimethylphenyl)phosphino]-1,1 inverted exclamation marka-spirobiindane; (S)-(-)-7,7 inverted exclamation marka-Bis[di(3,5-dimethylphenyl)phosphino]-2,2 inverted exclamation marka,3,3 inverted exclamation marka-tetrahydro-1,1 inverted exclamation marka-spirobiindene 528521-89-3 AB1005816 is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-(-)-7,7 inverted exclamation marka-Bis[di(3,5-dimethylphenyl)phosphino]-1,1 inverted exclamation marka-spirobiindane; (S)-(-)-7,7 inverted exclamation marka-Bis[di(3,5-dimethylphenyl)phosphino]-2,2 inverted exclamation marka,3,3 inverted exclamation marka-tetrahydro-1,1 inverted exclamation marka-spirobiindene 528521-89-3 AB1005816 (CAS 528521-89-3), a certified reference material (molecular formula C49H86P2, MW 737.15 g/mol) for analytical method development and quality control.

(S)-(-)-7,7 inverted exclamation marka-Bis[di(3,5-dimethylphenyl)phosphino]-1,1 inverted exclamation marka-spirobiindane; (S)-(-)-7,7 inverted exclamation marka-Bis[di(3,5-dimethylphenyl)phosphino]-2,2 inverted exclamation marka,3,3 inverted exclamation marka-tetrahydro-1,1 inverted exclamation marka-spirobiindene 528521-89-3 AB1005816 (C49H86P2) contains organophosphorus functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (S)-(-)-7,7 inverted exclamation marka-Bis[di(3,5-dimethylphenyl)phosphino]-1,1 inverted exclamation marka-spirobiindane; (S)-(-)-7,7 inverted exclamation marka-Bis[di(3,5-dimethylphenyl)phosphino]-2,2 inverted exclamation marka,3,3 inverted exclamation marka-tetrahydro-1,1 inverted exclamation marka-spirobiindene 528521-89-3 AB1005816 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.
