Ubidecarenone — impurities and related standards

All 4 Ubidecarenone-related compounds in the CATO catalogue, listed with their CAS numbers, molecular formulae and stock status. If the compound you need is not listed, send the structure or the impurity designation and we will check whether it can be synthesised or isolated.

Ubidecarenone, also known as coenzyme Q10, is a benzoquinone bearing a ten-unit isoprenoid side chain; it functions as an electron carrier in mitochondrial respiration and is used as a pharmaceutical and nutritional ingredient. Its impurity profile is governed by that long side chain, which gives rise to related substances differing in isoprene chain length, cis and trans geometry or hydrogenation state, together with oxidised and reduced forms of the quinone ring. The page brings together the EP-designated ubidecarenone impurities and further non-compendial related substances, including coenzyme Q10 itself and an isomeric mixture, each provided as a separate characterised lot for identification and related-substance analysis.
