2-Ethynylisonicotinaldehyde CAS 1211536-16-1 chemical structure

Description

As a certified reference material (CRM), 2-Ethynylisonicotinaldehyde 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-Ethynylisonicotinaldehyde (CAS 1211536-16-1), a certified reference material (molecular formula C8H5NO, MW 131.13 g/mol) for analytical method development and quality control.

2-Ethynylisonicotinaldehyde (C8H5NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
