Nandrolone Phenylpropionate​ Powder

Nandrolone Phenylpropionate​

Nandrolone Phenylpropionate​ is an esterified derivative of nandrolone belonging to the anabolic-androgenic steroid class. Also known as nandrolone phenpropionate, it is formed by attaching a 3-phenylpropionate ester to the nandrolone structure. This modification gives the compound a distinct molecular profile compared with unesterified nandrolone and other nandrolone esters.

What Is Nandrolone Phenylpropionate​?

Nandrolone Phenylpropionate​ is a synthetic steroid compound structurally related to nandrolone, which itself is a 19-nortestosterone derivative. The phenylpropionate ester is attached at the 17-position of the steroid structure, creating a compound with the molecular formula C₂₇H₃₄O₃ and a molecular weight of approximately 406.6 g/mol. Its CAS Registry Number is 62-90-8.

The compound is listed in chemical databases under several related names, including nandrolone phenpropionate, nortestosterone phenylpropionate, norandrolone phenylpropionate, and NTPP. These names can be useful when comparing chemical literature, analytical references, and research databases.

Chemical Structure and Properties

The molecular structure of Nandrolone Phenylpropionate​ combines the characteristic steroid nucleus of nandrolone with a phenylpropionate ester group. According to PubChem, the compound has an XLogP3 value of approximately 5.1, a topological polar surface area of 43.4 Ų, and three hydrogen-bond acceptors. PubChem also reports an exact mass of approximately 406.2508 Da.

As an esterified steroid, its chemical characteristics differ from those of nandrolone itself. The additional phenylpropionate portion contributes to the compound’s molecular weight, lipophilicity, and overall structure. Understanding these differences is particularly relevant when studying steroid chemistry, analytical identification, and structure–property relationships.

Nandrolone Phenylpropionate​ vs. Nandrolone

Although this chemical​ is derived from nandrolone, the two compounds should not be treated as identical chemicals. Nandrolone represents the underlying steroid structure, while Nandrolone Phenylpropionate​ contains the additional 3-phenylpropionate ester. This structural distinction affects the compound’s physical and chemical characteristics.

It is also important not to confuse Nandrolone Phenylpropionate​ with nandrolone propionate. They are different chemical compounds. Nandrolone propionate has the molecular formula C₂₁H₃₀O₃ and a molecular weight of approximately 330.5 g/mol, whereas this chemical contains the larger phenylpropionate ester and has a molecular weight of approximately 406.6 g/mol.

Research and Analytical Relevance

Nandrolone Phenylpropionate​ has been documented in pharmaceutical and scientific literature and is represented in major chemical databases. Its defined molecular structure, CAS number, molecular formula, and other identifiers make it suitable for chemical reference, analytical research, and studies involving steroid structures.

For researchers working with steroid compounds, accurate identification is particularly important because closely related nandrolone esters can have substantially different molecular formulas and physical characteristics. Analytical work may therefore distinguish this chemical​ from nandrolone, nandrolone propionate, and other esterified derivatives.
