Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[2-(Morpholin-4-yl)ethyl]-2H,3H,4H-pyrido[3,2-b][1,4]oxazin-3-one.
2-[2-(Morpholin-4-yl)ethyl]-2H,3H,4H-pyrido[3,2-b][1,4]oxazin-3-one (CAS 860611-77-4), molecular formula C13H17N3O3 and molecular weight 263.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-[2-(Morpholin-4-yl)ethyl]-2H,3H,4H-pyrido[3,2-b][1,4]oxazin-3-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.29 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-[2-(Morpholin-4-yl)ethyl]-2H,3H,4H-pyrido[3,2-b][1,4]oxazin-3-one 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.
