Description
CATO manufactures 5-Fluorospiro[indoline-3,4'-piperidine] 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.
5-Fluorospiro[indoline-3,4'-piperidine] (CAS 944905-36-6) is a high-purity analytical reference standard with the molecular formula C12H15FN2 and a molecular weight of 206.26 g/mol.
The molecular framework of 5-Fluorospiro[indoline-3,4'-piperidine] (C12H15FN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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).
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.
