4-Ethyl-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-amine CAS 1884222-67-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Ethyl-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-amine.

4-Ethyl-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-amine (CAS 1884222-67-6), molecular formula C9H13N3O and molecular weight 179.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Ethyl-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-amine (C9H13N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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), 4-Ethyl-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-amine 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.
