The occurrence of N-Desisobutyl-N-propyl Rifabutin is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-Desisobutyl-N-propyl Rifabutin (CAS 75903-10-5), molecular formula C45H60N4O11 and molecular weight 832.98 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, N-Desisobutyl-N-propyl Rifabutin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 832.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
