Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl 7-hydroxy-2-azaspiro[4.4]nonane-2-carboxylate 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.
tert-Butyl 7-hydroxy-2-azaspiro[4.4]nonane-2-carboxylate (CAS 1319716-41-0), molecular formula C13H23NO3 and molecular weight 241.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl 7-hydroxy-2-azaspiro[4.4]nonane-2-carboxylate (C13H23NO3) is characterized by an amide group, a carboxylic acid 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
