Chemical Structure
Description
The molecular framework of 5'-Chloro-2',3'-dihydrospiro[azetidine-2,1'-indene] (C11H12ClN) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5'-Chloro-2',3'-dihydrospiro[azetidine-2,1'-indene] (CAS 1934841-09-4) is a high-purity analytical reference standard with the molecular formula C11H12ClN and a molecular weight of 193.67 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), 5'-Chloro-2',3'-dihydrospiro[azetidine-2,1'-indene] 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.
