Chemical Structure
Description
The molecular framework of 1-(Pyrrolidin-3-yl)-1H-1,3-benzodiazole (C11H13N3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-(Pyrrolidin-3-yl)-1H-1,3-benzodiazole (CAS 1249145-08-1) is a high-purity analytical reference standard with the molecular formula C11H13N3HCl and a molecular weight of 223.70 g/mol.
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.
As a certified reference material (CRM), 1-(Pyrrolidin-3-yl)-1H-1,3-benzodiazole 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.
