Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 163.60 g/mol gives 3-Chloro-3-phenylacrylonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Chloro-3-phenylacrylonitrile (CAS 78583-84-3), molecular formula C9H6ClN and molecular weight 163.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-3-phenylacrylonitrile (C9H6ClN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 3-Chloro-3-phenylacrylonitrile 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.
