Description

CATO supplies (1R,3S,E)-5-((E)-2-((1R,3aS,7aR)-1-((2R,5S,E)-5-Cyclopropyl-5-hydroxypent-3-en-2-yl)-7a-methylhexahydro-1H-inden-4(2H)-ylidene)ethylidene)-4-methylenecyclohexane-1,3-diol (CAS 910133-70-9), a certified reference material (molecular formula C27H40O3, MW 412.60 g/mol) for analytical method development and quality control.

Structurally, (1R,3S,E)-5-((E)-2-((1R,3aS,7aR)-1-((2R,5S,E)-5-Cyclopropyl-5-hydroxypent-3-en-2-yl)-7a-methylhexahydro-1H-inden-4(2H)-ylidene)ethylidene)-4-methylenecyclohexane-1,3-diol (C27H40O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 412.60 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
