Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((4-((Trimethylsilyl)ethynyl)-phenyl)ethynyl)phenol.
4-((4-((Trimethylsilyl)ethynyl)-phenyl)ethynyl)phenol (CAS 910467-75-3) is a high-purity analytical reference standard with the molecular formula C19H18OSi and a molecular weight of 290.43 g/mol.
Structurally, 4-((4-((Trimethylsilyl)ethynyl)-phenyl)ethynyl)phenol (C19H18OSi) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 290.43 g/mol, it falls into the medium-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.
As a certified reference material (CRM), 4-((4-((Trimethylsilyl)ethynyl)-phenyl)ethynyl)phenol 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.
