Lithium 5-(1-(methylsulfonyl)cyclopropyl)-1,3,4-oxadiazole-2-carboxylate CAS 2773477-78-2 chemical structure

Description

The occurrence of Lithium 5-(1-(methylsulfonyl)cyclopropyl)-1,3,4-oxadiazole-2-carboxylate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Lithium 5-(1-(methylsulfonyl)cyclopropyl)-1,3,4-oxadiazole-2-carboxylate (CAS 2773477-78-2) is a high-purity analytical reference standard with the molecular formula C7H7N2O5SLi and a molecular weight of 238.14 g/mol.

The molecular framework of Lithium 5-(1-(methylsulfonyl)cyclopropyl)-1,3,4-oxadiazole-2-carboxylate (C7H7N2O5SLi) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.

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.

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.
