Chemical Structure
Description
Benzyl 2-(benzyloxy)-2-methylpropanoate (CAS 347400-73-1), molecular formula C18H20O3 and molecular weight 284.35 g/mol, is a CATO reference standard with documented purity and traceability.
Benzyl 2-(benzyloxy)-2-methylpropanoate (C18H20O3) contains a steroid core, 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), Benzyl 2-(benzyloxy)-2-methylpropanoate 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.
