Chemical Structure

1-Tosylpyrrolidin-3-one CAS 73696-28-3 chemical structure

Description

The occurrence of 1-Tosylpyrrolidin-3-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Tosylpyrrolidin-3-one (CAS 73696-28-3), molecular formula C11H13NO3S and molecular weight 239.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H13NO3S, 1-Tosylpyrrolidin-3-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 239.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
