4-(Dimethylamino)pyridine N-Oxide CAS 1005-31-8 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-(Dimethylamino)pyridine N-Oxide (CAS 1005-31-8) is a high-purity analytical reference standard with the molecular formula C7H10N2O and a molecular weight of 138.17 g/mol.

The molecular framework of 4-(Dimethylamino)pyridine N-Oxide (C7H10N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-(Dimethylamino)pyridine N-Oxide 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.
