Chemical Structure
Description
The molecular framework of 5-chloro-2,3-dihydrospiro[indene-1,3'-pyrrolidine] (C12H20ClN) is characterized by 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
5-chloro-2,3-dihydrospiro[indene-1,3'-pyrrolidine] (CAS 956141-91-6), molecular formula C12H20ClN and molecular weight 213.75 g/mol, is a CATO reference standard with documented purity and traceability.
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 5-chloro-2,3-dihydrospiro[indene-1,3'-pyrrolidine] 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.
