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 supplies 2-(4-Chloro-3,5-dimethyl-1H-pyrazol-1-yl)-N-(2-(dimethylamino)ethyl)acetamide (CAS 1245570-18-6), a certified reference material (molecular formula C11H19ClN4O, MW 258.75 g/mol) for analytical method development and quality control.
2-(4-Chloro-3,5-dimethyl-1H-pyrazol-1-yl)-N-(2-(dimethylamino)ethyl)acetamide (C11H19ClN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 2-(4-Chloro-3,5-dimethyl-1H-pyrazol-1-yl)-N-(2-(dimethylamino)ethyl)acetamide 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.
