Chemical Structure
Description
2-((2-Hydroxyethyl)(methyl)amino)ethyl hydrogen phenylboronate (CAS 65796-77-2), molecular formula C11H18BNO3 and molecular weight 223.08 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H18BNO3, 2-((2-Hydroxyethyl)(methyl)amino)ethyl hydrogen phenylboronate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 223.08 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-((2-Hydroxyethyl)(methyl)amino)ethyl hydrogen phenylboronate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
