Application: 5-α-Cholestane has been used:
• as an internal standard in gas phase chromatography (GC) and high-performance liquid chromatography (HPLC) to quantify cholesterol in meat products for a comparison study
• to quantify the active compounds in the oils using a gas chromatograph coupled to a mass spectrometer
• as a reference standard in GC analyses to quantify sterol content in the unsaponifiables obtained from oat lipids and different sterol standards like fucosterol, sitosterol, campesterol, and stigmasterol
Biochem/physiol Actions: 5α-Cholestane is a sterol produced endogenously from cholesterol and has been isolated from human feces. It is derived from cholesterol by the action of intestinal microorganisms. Derivatives of 5α-cholestane in plants are called brassinosteroids that selectively activate the PPI3K/Akt pathway.
Packaging: 1, 5 g in glass bottle
Packaging: 100 mg in poly bottle
Preparation Note: 5α-Cholestane yields clear to slightly hazy, colorless to faint yellow solution in chloroform at 50 mg/ml.

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
