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-((3-Methyl-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)acetic acid (CAS 842972-52-5), molecular formula C8H8N4O3 and molecular weight 208.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((3-Methyl-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)acetic acid (C8H8N4O3) 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-((3-Methyl-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)acetic acid 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.
