Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 181647-10-9 4-[N-Ethyl-(4-methoxyphenyl)methylamino]-2-butynyl-2-cyclohexyl-2-hydroxybenzene Acetate |A-Cyclohexyl-|A-hydroxy-benzeneacetic Acid 4-[Ethyl[(4-methoxyphenyl)methyl]amino]-2-butyn-1-yl Ester.

181647-10-9 4-[N-Ethyl-(4-methoxyphenyl)methylamino]-2-butynyl-2-cyclohexyl-2-hydroxybenzene Acetate |A-Cyclohexyl-|A-hydroxy-benzeneacetic Acid 4-[Ethyl[(4-methoxyphenyl)methyl]amino]-2-butyn-1-yl Ester (CAS 181647-10-9), molecular formula C28H35NO4 and molecular weight 449.58 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 181647-10-9 4-[N-Ethyl-(4-methoxyphenyl)methylamino]-2-butynyl-2-cyclohexyl-2-hydroxybenzene Acetate |A-Cyclohexyl-|A-hydroxy-benzeneacetic Acid 4-[Ethyl[(4-methoxyphenyl)methyl]amino]-2-butyn-1-yl Ester (C28H35NO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 449.58 g/mol, it falls into the moderately-high-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
