Chemical Structure
Description
The occurrence of N-(cyclopentylmethyl)-3-ethynylaniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(cyclopentylmethyl)-3-ethynylaniline (CAS 1248631-23-3), molecular formula C14H17N and molecular weight 199.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(cyclopentylmethyl)-3-ethynylaniline (C14H17N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-(cyclopentylmethyl)-3-ethynylaniline 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.
