Chemical Structure
Description
The molecular framework of N-[1-(2-cyanoethyl)-3-methyl-1H-pyrazol-5-yl]acetamide (C9H12N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. 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).
N-[1-(2-cyanoethyl)-3-methyl-1H-pyrazol-5-yl]acetamide (CAS 1181457-80-6), molecular formula C9H12N4O and molecular weight 192.22 g/mol, is a CATO reference standard with documented purity and traceability.
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-[1-(2-cyanoethyl)-3-methyl-1H-pyrazol-5-yl]acetamide 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.
