Chemical Structure
Description
The molecular framework of 4-(Phenylamino)-3-propyl-1H-1,2,4-triazol-5(4H)-one (C11H14N4O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-(Phenylamino)-3-propyl-1H-1,2,4-triazol-5(4H)-one (CAS 75989-68-3), molecular formula C11H14N4O and molecular weight 218.26 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), 4-(Phenylamino)-3-propyl-1H-1,2,4-triazol-5(4H)-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.
