A-D2PV Crystal Chemical Structure, Crystal Properties, Research and Safety Information

What is the A-D2PV crystal?

A-D2PV (also written as α-D2PV) is a synthetic cathinone-related compound that has been described in forensic and research literature. 1,2-diphenyl-2-(pyrrolidin-1-yl)ethan-1-one is the systematic chemical name. The molecular formula of the free-base form was reported as C18H19NO with a molecular weight of approximately 265.36 g/mol.

A-D2PV is not a standard pharmaceutical product and has no recognised therapeutic indication. It is mainly found in the area of novel psychoactive substances (NPS) and forensic chemistry. Consequently, very little is known about its pharmacology, toxicity and long-term effects.

Chemical Structure A-DPV

A-D2PV consists of two phenyl rings, carbonyl group and nitrogen containing ring of pyrrolidine. The arrangement of the molecules gives the compound a unique chemical structure that researchers can identify using analytical techniques.

A forensic analytical report identified the compound as 1,2-diphenyl 2-(pyrrolidin-1-yl) ethan-1-one and reported the formula as C18H19NO. The same report also specified hydrochloride as a salt form in the sample analysed.

A-D2PV Kristallstruktur

The word “crystal” refers to the physical crystalline form of the compound and is not a separate therapeutic product. The A-D2PV crystals have been studied by scientific researchers using single-crystal X-ray diffraction, mass spectrometry and infrared spectroscopy.

In 2024, Acta Crystallographica Section C published a study on α-D2PV hydrochloride from a seized sample. Researchers found crystalline α-D2PV hydrochloride in myo-inositol. The study described the molecular interactions in the crystal such as hydrogen bonding involving chloride ions and π–π interactions between aromatic rings.

What does a crystal analysis show?

Scientists can determine, through crystal analysis:

1. The three-dimensional molecular framework.
2. Identity of a chemical compound.
3. Intermolecular interactions.
4. Salts and hydrates.
5. Differences between similar chemical structures.

Therefore, crystallography provides valuable information for forensic and analytical chemistry.

Synthetic Cathinones & A-D2PV

A-D2PV is one of a larger group of compounds related to the synthetic cathinones. These compounds are structurally related to cathinone derivatives and have emerged within the framework of novel psychoactive substances.

However, researchers stress that little is known about the pharmacology of α-D2PV. The scientific literature is not rich enough in evidence to establish safe medical applications or predictable effects.

The Importance of A-D2PV Studies

A-D2PV has utility in analytical and forensic research, despite the limited pharmacological information. Scientists can study its molecular framework, crystal packing, analytical signatures and relation to other novel psychoactive substances.

A 2025 crystallographic publication also compared A-D2PV hydrochloride with α-PVP hydrochloride and showed how X-ray crystallisation can differentiate between related pyrrolidine-containing compounds.

The Facts on A-D2PV Crystal
