Hydrocortisone-d4
Cortisol measurement underpins adrenal function testing, and Hydrocortisone-d4 supplies the stable-isotope counterpart that makes those measurements defensible. Four deuterium atoms sit on the steroid nucleus, so the labelled molecule follows the analyte through extraction, derivatisation and chromatography while remaining distinguishable by mass. Laboratories rely on such a standard when building and validating LC-MS/MS methods for serum, plasma, urine and saliva, when confirming peak identity as interferences appear, and when correcting for ion suppression and recovery losses in quantitative runs. It is a white to off-white solid of formula C21H26D4O5 and molecular weight 366.48, listed in 0.5 mg, 1 mg, 5 mg and 10 mg pack sizes. Store at -20 +/- 5 C and ship with ice packs to protect chemical and isotopic integrity in transit. A quotation or the supporting documentation can be supplied on request.
