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.
(3|A,25R)-Spirost-5-en-3-ol Benzoate 3-O-Benzoyl Diosgenine 4952-68-5 Diosgenin Benzoate (CAS 4952-68-5), molecular formula C34H46O4 and molecular weight 518.73 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (3|A,25R)-Spirost-5-en-3-ol Benzoate 3-O-Benzoyl Diosgenine 4952-68-5 Diosgenin Benzoate (C34H46O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 518.73 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
