Chemical Structure
Description
phenyl trans-7-(m-tolyl)-2-oxaspiro[3.3]heptane-6-carboxylate (CAS 2624261-56-7), molecular formula C20H32O3 and molecular weight 320.47 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, phenyl trans-7-(m-tolyl)-2-oxaspiro[3.3]heptane-6-carboxylate (C20H32O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 320.47 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.
