N-(2-(Ethylsulfonyl)ethyl)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-carboxamide CAS 1428366-89-5

Description

Compared with other compounds in its class, the molecular weight of 287.34 g/mol gives N-(2-(Ethylsulfonyl)ethyl)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies N-(2-(Ethylsulfonyl)ethyl)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-carboxamide (CAS 1428366-89-5), a certified reference material (molecular formula C11H17N3O4S, MW 287.34 g/mol) for analytical method development and quality control.

The molecular framework of N-(2-(Ethylsulfonyl)ethyl)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-carboxamide (C11H17N3O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).

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), N-(2-(Ethylsulfonyl)ethyl)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-carboxamide 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.
