Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4'-Bromo-[1,1'-biphenyl]-4-yl)trimethylsilane.
(4'-Bromo-[1,1'-biphenyl]-4-yl)trimethylsilane (CAS 17908-91-7), molecular formula C15H17BrSi and molecular weight 305.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, a polycyclic aromatic system, (4'-Bromo-[1,1'-biphenyl]-4-yl)trimethylsilane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures (4'-Bromo-[1,1'-biphenyl]-4-yl)trimethylsilane 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.
