Chemical Structure

Cis-2-pentenenitrile CAS 25899-50-7 chemical structure

Description

The occurrence of Cis-2-pentenenitrile is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Cis-2-pentenenitrile (CAS 25899-50-7), a certified reference material (molecular formula C5H7N, MW 81.12 g/mol) for analytical method development and quality control.

The molecular framework of Cis-2-pentenenitrile (C5H7N) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
