(2-ethynylphenyl)trimethylsilane CAS 78905-09-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-ethynylphenyl)trimethylsilane.

(2-ethynylphenyl)trimethylsilane (CAS 78905-09-6) is a high-purity analytical reference standard with the molecular formula C11H14Si and a molecular weight of 174.31 g/mol.

Owing to an aromatic ring system, (2-ethynylphenyl)trimethylsilane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 174.31 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).

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), (2-ethynylphenyl)trimethylsilane 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.
