Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 210.07 g/mol gives 4-Bromo-3-ethylbenzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-3-ethylbenzonitrile (CAS 170230-29-2), a certified reference material (molecular formula C9H8BrN, MW 210.07 g/mol) for analytical method development and quality control.
4-Bromo-3-ethylbenzonitrile (C9H8BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 4-Bromo-3-ethylbenzonitrile 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.
