Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-(2-amino[1,2,4]triazolo[1,5-a]pyrimidin-7-yl)-3-(2-chloro-6-fluorophenyl)propanoate.
Ethyl 2-(2-amino[1,2,4]triazolo[1,5-a]pyrimidin-7-yl)-3-(2-chloro-6-fluorophenyl)propanoate (CAS 477856-20-5), molecular formula C16H15ClFN5O2 and molecular weight 363.77 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H15ClFN5O2, Ethyl 2-(2-amino[1,2,4]triazolo[1,5-a]pyrimidin-7-yl)-3-(2-chloro-6-fluorophenyl)propanoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 363.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Ethyl 2-(2-amino[1,2,4]triazolo[1,5-a]pyrimidin-7-yl)-3-(2-chloro-6-fluorophenyl)propanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
