Description
Compared with other compounds in its class, the molecular weight of 257.35 g/mol gives 3-Isobutyl-5-isothiocyanato-1-phenyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Isobutyl-5-isothiocyanato-1-phenyl-1H-pyrazole (CAS 1349718-51-9), a certified reference material (molecular formula C14H15N3S, MW 257.35 g/mol) for analytical method development and quality control.
3-Isobutyl-5-isothiocyanato-1-phenyl-1H-pyrazole (C14H15N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-Isobutyl-5-isothiocyanato-1-phenyl-1H-pyrazole 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.
