Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Nitropyridine-d4 N-Oxide (CAS 119673-94-8) is a high-purity analytical reference standard with the molecular formula C5D4N2O3 and a molecular weight of 144.12 g/mol.
Owing to deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Nitropyridine-d4 N-Oxide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 4-Nitropyridine-d4 N-Oxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
