Description

Compared with other compounds in its class, the molecular weight of 138.17 g/mol gives 4-(Dimethylamino)pyridin-2(1H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(Dimethylamino)pyridin-2(1H)-one (CAS 65491-43-2) 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)pyridin-2(1H)-one (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. 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.

As a certified reference material (CRM), 4-(Dimethylamino)pyridin-2(1H)-one 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.
