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 2-(2-cyclopropylethynyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1432491-43-4), a certified reference material (molecular formula C11H17BO2, MW 192.06 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2-cyclopropylethynyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C11H17BO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 2-(2-cyclopropylethynyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
