Description

The occurrence of (4R,6R)-4-hydroxy-6-(2-((1S,2S,8S,8aR)-8-hydroxy-2-methyl-1,2,6,7,8,8a-hexahydronaphthalen-1-yl)ethyl)tetrahydro-2H-pyran-2-one is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4R,6R)-4-hydroxy-6-(2-((1S,2S,8S,8aR)-8-hydroxy-2-methyl-1,2,6,7,8,8a-hexahydronaphthalen-1-yl)ethyl)tetrahydro-2H-pyran-2-one (CAS 58889-19-3), molecular formula C18H26O4 and molecular weight 306.40 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (4R,6R)-4-hydroxy-6-(2-((1S,2S,8S,8aR)-8-hydroxy-2-methyl-1,2,6,7,8,8a-hexahydronaphthalen-1-yl)ethyl)tetrahydro-2H-pyran-2-one (C18H26O4) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 306.40 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
