Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 184.06 g/mol gives N,N-bis(2-chloroethyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N,N-bis(2-chloroethyl)acetamide (CAS 19945-22-3), molecular formula C6H11Cl2NO and molecular weight 184.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N,N-bis(2-chloroethyl)acetamide (C6H11Cl2NO) is characterized by 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), N,N-bis(2-chloroethyl)acetamide 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.
