Chemical Structure

Niobium potassium isopropoxide, 2.5% w/v in isopropanol CAS 21864-23-3 chemical structure

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 Niobium potassium isopropoxide, 2.5% w/v in isopropanol (CAS 21864-23-3), a certified reference material (molecular formula C9H21NbO3C3H7OK, MW 368.36 g/mol) for analytical method development and quality control.

Niobium potassium isopropoxide, 2.5% w/v in isopropanol (C9H21NbO3C3H7OK) 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 manufactures Niobium potassium isopropoxide, 2.5% w/v in isopropanol 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.
