Chemical Structure
Description
As a certified reference material (CRM), 2-Ethynyl-1-methyl-3-nitrobenzene 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 2-Ethynyl-1-methyl-3-nitrobenzene (CAS 1353714-73-4), a certified reference material (molecular formula C9H7NO2, MW 161.16 g/mol) for analytical method development and quality control.
2-Ethynyl-1-methyl-3-nitrobenzene (C9H7NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
