[4-(Trimethylsilyl)phenyl]acetic acid CAS 5112-65-2

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, [4-(Trimethylsilyl)phenyl]acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.33 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).

[4-(Trimethylsilyl)phenyl]acetic acid (CAS 5112-65-2), molecular formula C11H16O2Si and molecular weight 208.33 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), [4-(Trimethylsilyl)phenyl]acetic acid 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.
