Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 256.30 g/mol gives (S)-tert-butyl (1-(methoxy(methyl)amino)-1-oxopent-4-yn-2-yl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-tert-butyl (1-(methoxy(methyl)amino)-1-oxopent-4-yn-2-yl)carbamate (CAS 208520-80-3), molecular formula C12H20N2O4 and molecular weight 256.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-tert-butyl (1-(methoxy(methyl)amino)-1-oxopent-4-yn-2-yl)carbamate (C12H20N2O4) 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. 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)-tert-butyl (1-(methoxy(methyl)amino)-1-oxopent-4-yn-2-yl)carbamate 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.
