Chemical Structure
Description
The occurrence of 5-(Pyrrolidin-1-yl)pentanenitrile is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(Pyrrolidin-1-yl)pentanenitrile (CAS 71888-57-8), molecular formula C9H16N2 and molecular weight 152.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, 5-(Pyrrolidin-1-yl)pentanenitrile is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 5-(Pyrrolidin-1-yl)pentanenitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
