Description
CATO supplies (S)-2-Chloro-6,7,7a,8,10,11-hexahydro-4H-pyrimido[6',1':2,3]pyrimido[6,1-c][1,4]oxazin-4-one (CAS 2756706-65-5), a certified reference material (molecular formula C10H12ClN3O2, MW 241.67 g/mol) for analytical method development and quality control.
Structurally, (S)-2-Chloro-6,7,7a,8,10,11-hexahydro-4H-pyrimido[6',1':2,3]pyrimido[6,1-c][1,4]oxazin-4-one (C10H12ClN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 241.67 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (S)-2-Chloro-6,7,7a,8,10,11-hexahydro-4H-pyrimido[6',1':2,3]pyrimido[6,1-c][1,4]oxazin-4-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.
