The occurrence of 4-[4-[4-(Diphenylmethoxy)-1-piperidinyl]-1-butyne]-α,α-dimethyl-benzeneacetic Acid Methyl Ester 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.
4-[4-[4-(Diphenylmethoxy)-1-piperidinyl]-1-butyne]-α,α-dimethyl-benzeneacetic Acid Methyl Ester (CAS 1159977-33-9), molecular formula C33H37NO3 and molecular weight 495.65 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, 4-[4-[4-(Diphenylmethoxy)-1-piperidinyl]-1-butyne]-α,α-dimethyl-benzeneacetic Acid Methyl Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 495.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
