5-Cyanopentanoic acid CAS 5264-33-5

Description

Compared with other compounds in its class, the molecular weight of 127.14 g/mol gives 5-Cyanopentanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Cyanopentanoic acid (CAS 5264-33-5), molecular formula C6H9NO2 and molecular weight 127.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5-Cyanopentanoic acid is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 5-Cyanopentanoic acid 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.
