Chemical Structure

4-Cyclopropoxy-5-ethylnicotinonitrile CAS 1243442-25-2 chemical structure

Description

CATO supplies 4-Cyclopropoxy-5-ethylnicotinonitrile (CAS 1243442-25-2), a certified reference material (molecular formula C11H12N2O, MW 188.23 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Cyclopropoxy-5-ethylnicotinonitrile is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 188.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 4-Cyclopropoxy-5-ethylnicotinonitrile 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.
