Chemical Structure
Description
The occurrence of 2-Chloro-n-ethyl-n-methylacetamide is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-n-ethyl-n-methylacetamide (CAS 2746-07-8), molecular formula C5H10ClNO and molecular weight 135.59 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-n-ethyl-n-methylacetamide (C5H10ClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Chloro-n-ethyl-n-methylacetamide 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.
