6-ethoxypyridine-2-carboxylic acid CAS 42955-22-6

Description

As a certified reference material (CRM), 6-ethoxypyridine-2-carboxylic acid 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.

6-ethoxypyridine-2-carboxylic acid (CAS 42955-22-6) is a high-purity analytical reference standard with the molecular formula C8H15NO3 and a molecular weight of 173.21 g/mol.

Based on its molecular formula C8H15NO3, 6-ethoxypyridine-2-carboxylic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 173.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
