Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
lithium(1+) ion 5-benzyl-1,3-oxazole-2-carboxylate (CAS 1803585-61-6), molecular formula C11H8NO3Li and molecular weight 209.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of lithium(1+) ion 5-benzyl-1,3-oxazole-2-carboxylate (C11H8NO3Li) 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.
