Description

1,3,5,7,9,11,13,15-Octavinylpentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane 69655-76-1 Octavinyloctasilasesquioxane PSS-Octavinyl substituted (CAS 69655-76-1), molecular formula C16H24O12Si8 and molecular weight 633.04 g/mol, is a CATO reference standard with documented purity and traceability.

1,3,5,7,9,11,13,15-Octavinylpentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane 69655-76-1 Octavinyloctasilasesquioxane PSS-Octavinyl substituted (C16H24O12Si8) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1,3,5,7,9,11,13,15-Octavinylpentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane 69655-76-1 Octavinyloctasilasesquioxane PSS-Octavinyl substituted 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.
