(S)-2-(4-chloro-2,5-difluorophenyl)pyrrolidine CAS 1269780-39-3

Description

The occurrence of (S)-2-(4-chloro-2,5-difluorophenyl)pyrrolidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-2-(4-chloro-2,5-difluorophenyl)pyrrolidine (CAS 1269780-39-3) is a high-purity analytical reference standard with the molecular formula C10H10ClF2N and a molecular weight of 217.64 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, (S)-2-(4-chloro-2,5-difluorophenyl)pyrrolidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
