Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-1-isobutyl-3-(propoxymethyl)-1H-pyrazole.
4-Bromo-1-isobutyl-3-(propoxymethyl)-1H-pyrazole (CAS 1855950-98-9), molecular formula C11H19BrN2O and molecular weight 275.19 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-1-isobutyl-3-(propoxymethyl)-1H-pyrazole (C11H19BrN2O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
