Authentic vitamin D532 (link) ((5Z,7E)-9,10-secostigmasta-5,7,10(19)-trien-3β-ol, CAS 71761-06-3, 85% chemical purity) was purchased from BOC Sciences, Shirley, NY 11967, USA. Sitosterol (Purity ≥ 95%) and 7-dehydrocholesterol (7-DHC) (Purity > 98%), were purchased from Sigma-Aldrich (Steinheim, Germany) and used as standards. Stock solutions of the standards were prepared in benzene (Fluka) and stored at −20 °C.

The cholesterol-d7 (>99%) reference standards were purchased from Avanti Polar Lipids (Alabaster, AL, USA). Desmosterol (>84%), 7-dehydrocholesterol (7-DHC, >95%), 7-hydroxycholesterol (7-OHC, >95%), cholesterol (>99%), lanosterol (>93%), stigmasterol (95%), campesterol (65%), ammonium acetate, butylated hydroxytoluene (BHT), and methyl-tert-butyl ether (MTBE) were obtained from Sigma-Aldrich (St. Louis, MO, USA). Cholesteryl ester 20:4 (>98%) and cholesteryl ester 14:0 (>98%) were purchased from Cayman Chemical Company (Ann Arbor, MI, USA). Water, methanol, chloroform, and isopropanol were liquid chromatography–mass spectrometry (LC-MS) grade (Fisher Scientific Co., Pittsburgh, PA, USA).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
