Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Trimethyl(2,3,5,6-tetrafluoro-4-(triphenylsilyl)phenyl)silane (CAS 20083-06-1), a certified reference material (molecular formula C27H24F4Si2, MW 480.64 g/mol) for analytical method development and quality control.
Structurally, Trimethyl(2,3,5,6-tetrafluoro-4-(triphenylsilyl)phenyl)silane (C27H24F4Si2) contains fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 480.64 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.
CATO manufactures Trimethyl(2,3,5,6-tetrafluoro-4-(triphenylsilyl)phenyl)silane 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.
