Chemical Structure

Pyrazinamide-d3 CAS 1432059-16-9 chemical structure

Description

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.

Pyrazinamide-d3 (CAS 1432059-16-9), molecular formula C5H2D3N3O and molecular weight 126.13 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H2D3N3O, Pyrazinamide-d3 contains deuterium isotope labeling, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 126.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
