(4-BORONOPHENYL)(PYRROLIDIN-1-YL)METHANONE 389621-81-2 4-BORONO-N-(1-PYRROLIDINYL)BENZAMIDE 4-PYRROLIDINYLCARBONYLPHENYLBORONIC ACID BC002043 BORONIC ACID, [4-(1-PYRROLIDINYLCARBONYL)PHENYL]- [4-(1-PYRROLIDINYLCARBONYL)PHENYL]-BORONIC ACID (CAS 389621-81-2), molecular formula C11H14BNO3 and molecular weight 219.04 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H14BNO3, (4-BORONOPHENYL)(PYRROLIDIN-1-YL)METHANONE 389621-81-2 4-BORONO-N-(1-PYRROLIDINYL)BENZAMIDE 4-PYRROLIDINYLCARBONYLPHENYLBORONIC ACID BC002043 BORONIC ACID, [4-(1-PYRROLIDINYLCARBONYL)PHENYL]- [4-(1-PYRROLIDINYLCARBONYL)PHENYL]-BORONIC ACID 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 219.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
