Chemical Structure

1,3-Bis(triethoxysilyl)benzene CAS 16067-99-5 chemical structure

Description

1,3-Bis(triethoxysilyl)benzene (CAS 16067-99-5), molecular formula C18H34O6Si2 and molecular weight 402.63 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,3-Bis(triethoxysilyl)benzene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 402.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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-Bis(triethoxysilyl)benzene 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.
