Chemical Structure

19-(tert-Butoxy)-19-oxononadecanoic acid CAS 1643852-37-2 chemical structure

Description

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.

19-(tert-Butoxy)-19-oxononadecanoic acid (CAS 1643852-37-2), molecular formula C23H44O4 and molecular weight 384.59 g/mol, is a CATO reference standard with documented purity and traceability.

19-(tert-Butoxy)-19-oxononadecanoic acid (C23H44O4) contains a carboxylic acid 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.

As a certified reference material (CRM), 19-(tert-Butoxy)-19-oxononadecanoic 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.
