Chemical Structure
Description
As a certified reference material (CRM), 3,5-Dichloro-3-(4-methylpiperazinomethyl) benzophenone 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 3,5-Dichloro-3-(4-methylpiperazinomethyl) benzophenone (CAS 898789-29-2), a certified reference material (molecular formula C19H20Cl2N2O, MW 363.28 g/mol) for analytical method development and quality control.
The molecular framework of 3,5-Dichloro-3-(4-methylpiperazinomethyl) benzophenone (C19H20Cl2N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
