Chemical Structure
Description
2,5-Pyridinedicarboxylic Acid 13C7,d3 (CAS 1246818-08-5), molecular formula [13C]7H2D3NO4 and molecular weight 177.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula [13C]7H2D3NO4, 2,5-Pyridinedicarboxylic Acid 13C7,d3 contains deuterium isotope labeling; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 177.09 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
