Chemical Structure

7,10-Bis[O-(Triethylsilyl)]-10-Deacetyl Baccatin III CAS 149107-84-6 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 7,10-Bis[O-(Triethylsilyl)]-10-Deacetyl Baccatin III is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 773.11 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).

7,10-Bis[O-(Triethylsilyl)]-10-Deacetyl Baccatin III (CAS 149107-84-6), molecular formula C41H64O10Si2 and molecular weight 773.11 g/mol, is a CATO reference standard with documented purity and traceability.

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), 7,10-Bis[O-(Triethylsilyl)]-10-Deacetyl Baccatin III 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.
