Chemical Structure
Description
7-Methyl-2-azaspiro[4.4]Nonane-4-carboxylic acid (CAS 251461-75-3) is a high-purity analytical reference standard with the molecular formula C10H17NO2 and a molecular weight of 183.25 g/mol.
7-Methyl-2-azaspiro[4.4]Nonane-4-carboxylic acid (C10H17NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 7-Methyl-2-azaspiro[4.4]Nonane-4-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.
