9,10-Bis((trimethylsilyl)ethynyl)anthracene CAS 18750-95-3

Description

Compared with other compounds in its class, the molecular weight of 370.63 g/mol gives 9,10-Bis((trimethylsilyl)ethynyl)anthracene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

9,10-Bis((trimethylsilyl)ethynyl)anthracene (CAS 18750-95-3), molecular formula C24H26Si2 and molecular weight 370.63 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a polycyclic aromatic system, 9,10-Bis((trimethylsilyl)ethynyl)anthracene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 9,10-Bis((trimethylsilyl)ethynyl)anthracene 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.
