Description

Compared with other compounds in its class, the molecular weight of 313.35 g/mol gives [(1S,2R)-1-Acetamido-1H,2H,3H-naphtho[2,1-b]pyran-2-yl]methyl acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

[(1S,2R)-1-Acetamido-1H,2H,3H-naphtho[2,1-b]pyran-2-yl]methyl acetate (CAS 318959-02-3), molecular formula C18H19NO4 and molecular weight 313.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [(1S,2R)-1-Acetamido-1H,2H,3H-naphtho[2,1-b]pyran-2-yl]methyl acetate (C18H19NO4) is characterized by a flavonoid core, 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.

As a certified reference material (CRM), [(1S,2R)-1-Acetamido-1H,2H,3H-naphtho[2,1-b]pyran-2-yl]methyl acetate 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.
