Compared with other compounds in its class, the molecular weight of 374.37 g/mol gives 10,11,12,13-Tetrahydro-5-phenoxydiindeno[7,1-de:1′,7′-fg][1,3,2]dioxaphosphocin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
10,11,12,13-Tetrahydro-5-phenoxydiindeno[7,1-de:1′,7′-fg][1,3,2]dioxaphosphocin (CAS 1119754-16-3), molecular formula C23H19O3P and molecular weight 374.37 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 10,11,12,13-Tetrahydro-5-phenoxydiindeno[7,1-de:1′,7′-fg][1,3,2]dioxaphosphocin (C23H19O3P) contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 374.37 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.
CATO manufactures 10,11,12,13-Tetrahydro-5-phenoxydiindeno[7,1-de:1′,7′-fg][1,3,2]dioxaphosphocin under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
