Description
As a certified reference material (CRM), (3,4-Bis((trimethylsilyl)ethynyl)hexa-3-en-1,5-diyne-1,6-diyl)bis(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.
(3,4-Bis((trimethylsilyl)ethynyl)hexa-3-en-1,5-diyne-1,6-diyl)bis(trimethylsilane) (CAS 55660-76-9), molecular formula C22H36Si4 and molecular weight 412.86 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an aromatic ring system, (3,4-Bis((trimethylsilyl)ethynyl)hexa-3-en-1,5-diyne-1,6-diyl)bis(trimethylsilane) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.86 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.
