Chemical Structure
Description
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.
CATO supplies (Oxybis(4,1-phenylene))bis(dimethylsilane) (CAS 13315-17-8), a certified reference material (molecular formula C16H22OSi2, MW 286.52 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, (Oxybis(4,1-phenylene))bis(dimethylsilane) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (Oxybis(4,1-phenylene))bis(dimethylsilane) 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.
