Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 251.12 g/mol gives 3-Bromo-4-(pyrrolidin-1-yl)benzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Bromo-4-(pyrrolidin-1-yl)benzonitrile (CAS 1260837-23-7), a certified reference material (molecular formula C11H11BrN2, MW 251.12 g/mol) for analytical method development and quality control.
The molecular framework of 3-Bromo-4-(pyrrolidin-1-yl)benzonitrile (C11H11BrN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-Bromo-4-(pyrrolidin-1-yl)benzonitrile 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.
