Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 133.97 g/mol gives 2-bromopropionitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-bromopropionitrile (CAS 19481-82-4), a certified reference material (molecular formula C3H4BrN, MW 133.97 g/mol) for analytical method development and quality control.
The molecular framework of 2-bromopropionitrile (C3H4BrN) is characterized by a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 2-bromopropionitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
