[(4-Methoxyphenyl)ethynyl]trimethylsilane CAS 3989-14-8

Description

Compared with other compounds in its class, the molecular weight of 204.34 g/mol gives [(4-Methoxyphenyl)ethynyl]trimethylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

[(4-Methoxyphenyl)ethynyl]trimethylsilane (CAS 3989-14-8) is a high-purity analytical reference standard with the molecular formula C12H16OSi and a molecular weight of 204.34 g/mol.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, [(4-Methoxyphenyl)ethynyl]trimethylsilane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.34 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), [(4-Methoxyphenyl)ethynyl]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.
