Chemical Structure
Description
As a certified reference material (CRM), (3-(N-(1-(Cyclohexylamino)-3-methyl-1-oxobutan-2-yl)acetamido)phenyl)boronic acid 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.
(3-(N-(1-(Cyclohexylamino)-3-methyl-1-oxobutan-2-yl)acetamido)phenyl)boronic acid (CAS 397843-90-2), molecular formula C19H29BN2O4 and molecular weight 360.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-(N-(1-(Cyclohexylamino)-3-methyl-1-oxobutan-2-yl)acetamido)phenyl)boronic acid (C19H29BN2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
