Chemical Structure
Description
The molecular framework of 7-Benzyl-7-azaspiro[3.5]Nonane-1-carboxylic acid (C16H21NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
7-Benzyl-7-azaspiro[3.5]Nonane-1-carboxylic acid (CAS 2306265-64-3), molecular formula C16H21NO2 and molecular weight 259.34 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.
As a certified reference material (CRM), 7-Benzyl-7-azaspiro[3.5]Nonane-1-carboxylic acid 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.
