Chemical Structure
Description
The occurrence of 2-Chloro-1-(1H-pyrrol-3-yl)ethanone is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Chloro-1-(1H-pyrrol-3-yl)ethanone (CAS 122450-28-6), a certified reference material (molecular formula C6H6ClNO, MW 143.57 g/mol) for analytical method development and quality control.
2-Chloro-1-(1H-pyrrol-3-yl)ethanone (C6H6ClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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-1-(1H-pyrrol-3-yl)ethanone 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.
