4-Acetyl-5-oxohexanenitrile CAS 21603-67-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 4-Acetyl-5-oxohexanenitrile (CAS 21603-67-8), a certified reference material (molecular formula C8H11NO2, MW 153.18 g/mol) for analytical method development and quality control.

4-Acetyl-5-oxohexanenitrile (C8H11NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 4-Acetyl-5-oxohexanenitrile 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.
