Chemical Structure
Description
Hafnium(IV) i-propoxide monoisopropylate, 99% (C12H28HfO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 supplies Hafnium(IV) i-propoxide monoisopropylate, 99% (CAS 2171-99-5), a certified reference material (molecular formula C12H28HfO4, MW 414.84 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
