Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,13-Bis((trimethylsilyl)ethynyl)pentacene.
CATO supplies 6,13-Bis((trimethylsilyl)ethynyl)pentacene (CAS 317809-68-0), a certified reference material (molecular formula C32H30Si2, MW 470.75 g/mol) for analytical method development and quality control.
Structurally, 6,13-Bis((trimethylsilyl)ethynyl)pentacene (C32H30Si2) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 470.75 g/mol, it falls into the moderately-high-molecular-weight range. 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.
