Chemical Structure

Dimethylsilyl acetate CAS 18243-23-7 chemical structure

Description

The occurrence of Dimethylsilyl acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dimethylsilyl acetate (CAS 18243-23-7) is a high-purity analytical reference standard with the molecular formula C4H10O2Si and a molecular weight of 118.21 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Dimethylsilyl acetate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 118.21 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), Dimethylsilyl acetate 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.
