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 1-(4-Chloro-7-methylpyrazolo[1,5-a][1,3,5]triazin-2-yl)ethan-1-one.
CATO supplies 1-(4-Chloro-7-methylpyrazolo[1,5-a][1,3,5]triazin-2-yl)ethan-1-one (CAS 2387597-03-5), a certified reference material (molecular formula C8H7ClN4O, MW 210.62 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Chloro-7-methylpyrazolo[1,5-a][1,3,5]triazin-2-yl)ethan-1-one (C8H7ClN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
