Chemical Structure
Description
As a certified reference material (CRM), (Z)-Pralidoxime Chloride 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.
CATO supplies (Z)-Pralidoxime Chloride (CAS 13698-37-8), a certified reference material (molecular formula C7H9N2OCl, MW 172.61 g/mol) for analytical method development and quality control.
The molecular framework of (Z)-Pralidoxime Chloride (C7H9N2OCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
