CATO supplies (R)-7-(2-methoxyacetyl)tetrahydro-1H-oxazolo[3,4-a]pyrazin-3(5H)-one 1795751-79-9 KS-00003KZ9 (CAS 1795751-79-9), a certified reference material (molecular formula C9H14N2O4, MW 214.22 g/mol) for analytical method development and quality control.
The molecular framework of (R)-7-(2-methoxyacetyl)tetrahydro-1H-oxazolo[3,4-a]pyrazin-3(5H)-one 1795751-79-9 KS-00003KZ9 (C9H14N2O4) is characterized by an amino-acid-derived structure, 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. 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.
