Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-Butyl(2-fluoro-5-nitrophenoxy)dimethylsilane (CAS 1881330-97-7) is a high-purity analytical reference standard with the molecular formula C12H18FNO3Si and a molecular weight of 271.36 g/mol.
Based on its molecular formula C12H18FNO3Si, tert-Butyl(2-fluoro-5-nitrophenoxy)dimethylsilane contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 tert-Butyl(2-fluoro-5-nitrophenoxy)dimethylsilane 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.
