Chemical Structure
Description
As a certified reference material (CRM), n-{[5-(2-chloroacetyl)thiophen-2-yl]methyl}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.
n-{[5-(2-chloroacetyl)thiophen-2-yl]methyl}acetamide (CAS 104082-15-7), molecular formula C9H10ClNO2S and molecular weight 231.70 g/mol, is a CATO reference standard with documented purity and traceability.
n-{[5-(2-chloroacetyl)thiophen-2-yl]methyl}acetamide (C9H10ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
