Description
CATO manufactures ((4-((4-((4-Ethynylphenyl)ethynyl)phenyl)ethynyl)-phenyl)ethynyl)triisopropylsilane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
((4-((4-((4-Ethynylphenyl)ethynyl)phenyl)ethynyl)-phenyl)ethynyl)triisopropylsilane (CAS 176977-38-1) is a high-purity analytical reference standard with the molecular formula C35H34Si and a molecular weight of 482.73 g/mol.
Structurally, ((4-((4-((4-Ethynylphenyl)ethynyl)phenyl)ethynyl)-phenyl)ethynyl)triisopropylsilane (C35H34Si) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 482.73 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
