Chemical Structure
Description
CATO supplies 2-(5-chloro-1,3-benzoxazol-2-yl)ethanamine,HCl (CAS 871688-91-4), a certified reference material (molecular formula C9H9ClN2O, MW 196.63 g/mol) for analytical method development and quality control.
The molecular framework of 2-(5-chloro-1,3-benzoxazol-2-yl)ethanamine,HCl (C9H9ClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
As a certified reference material (CRM), 2-(5-chloro-1,3-benzoxazol-2-yl)ethanamine,HCl 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.
