Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(6-Oxo-3-(1H-pyrazol-1-yl)pyridazin-1(6H)-yl)acetic acid.
2-(6-Oxo-3-(1H-pyrazol-1-yl)pyridazin-1(6H)-yl)acetic acid (CAS 1334373-79-3), molecular formula C9H8N4O3 and molecular weight 220.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(6-Oxo-3-(1H-pyrazol-1-yl)pyridazin-1(6H)-yl)acetic acid (C9H8N4O3) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
