methyl 4H,5H,6H,7H,8H-cyclohepta[d][1,2]oxazole-3-carboxylate (CAS 1803611-76-8), molecular formula C10H13NO3 and molecular weight 195.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl 4H,5H,6H,7H,8H-cyclohepta[d][1,2]oxazole-3-carboxylate (C10H13NO3) 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 its high hydrophobicity (logP), 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.
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.
