Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl 2-(triphenylphosphoranylidene)acetate 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 2-(triphenylphosphoranylidene)acetate (CAS 35000-38-5), molecular formula C24H25O2P and molecular weight 376.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, tert-Butyl 2-(triphenylphosphoranylidene)acetate (C24H25O2P) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 376.43 g/mol, it falls into the moderately-high-molecular-weight range. 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.
