Tacrolimus is a macrolide immunosuppressant whose narrow therapeutic range makes related-substance control essential, and Oxacyclohexane Open Ring Tacrolimus is one of the compounds examined in that work. The name describes a ring-opened analogue in which the oxacyclohexane portion of the macrocycle is no longer intact, giving formula C44H71NO13 and molecular weight 822.03. It serves analytical laboratories as a marker for peak identification in related-substance methods, as a system-suitability check, and as a calibration material when such analogues are determined against external standards. Listed pack sizes begin at 1 mg and extend to 500 mg, with 10 mg, 20 mg, 25 mg, 50 mg and 100 mg among the intermediate options. Store at -20 +/- 5 C and ship with ice packs. A quotation or the supporting documentation can be provided on request.
