5-(4-Fluoropyrrolidin-2-yl)-3-methyl-1,2,4-oxadiazole CAS 1934689-66-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(4-Fluoropyrrolidin-2-yl)-3-methyl-1,2,4-oxadiazole.

5-(4-Fluoropyrrolidin-2-yl)-3-methyl-1,2,4-oxadiazole (CAS 1934689-66-3), molecular formula C7H10FN3O and molecular weight 171.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(4-Fluoropyrrolidin-2-yl)-3-methyl-1,2,4-oxadiazole (C7H10FN3O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 171.17 g/mol, it falls into the medium-molecular-weight range. 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.

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.
