Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Ethoxy-1-(1-methyl-1H-pyrazol-4-yl)ethan-1-one (CAS 1104291-93-1), molecular formula C8H12N2O2 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Ethoxy-1-(1-methyl-1H-pyrazol-4-yl)ethan-1-one (C8H12N2O2) is characterized by an amino-acid-derived structure, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-Ethoxy-1-(1-methyl-1H-pyrazol-4-yl)ethan-1-one 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.
