Product Description
4-Azepanone HCl is a biochemical compound that could be utilized as a biomaterial or organic/chemical reagent for biomedical research.
4-Azepanone hydrochloride (CAS 50492-22-3), also known as hexahydro-4-azepinone hydrochloride, is a cyclic ketone with the molecular formula C₆H₁₂ClNO. It appears as a white to orange to green powder with a purity of ≥98% (argentometric titration) and ≥97% (nonaqueous titration). This compound is a biochemical reagent that can be utilized as a biomaterial or organic/chemical reagent for biomedical research. As a seven-membered ring ketone with a nitrogen atom, 4-azepanone hydrochloride is a versatile building block for the synthesis of various heterocyclic compounds and pharmaceutical intermediates.
Biological Activity I Assay Protocols (From Reference)
Targets
4-Azepanone hydrochloride does not have a defined primary drug target as it is a chemical reagent and synthetic building block rather than a therapeutic agent. The azepanone (seven-membered lactam) core is found in various pharmacologically active compounds, including certain kinase inhibitors, protease inhibitors, and CNS-active agents. The ketone and amine functionalities enable diverse derivatization to create molecules that interact with specific biological targets. As a synthetic intermediate, the compound itself is not designed to bind to specific proteins or receptors in a therapeutic context.
ln Vitro
As a synthetic reagent, 4-Azepanone hydrochloride is not typically evaluated for direct in vitro biological activity against specific molecular targets. The compound serves as a precursor for biologically active molecules rather than possessing intrinsic pharmacological activity. Its primary applications are in organic synthesis as a building block for heterocyclic compounds and pharmaceutical intermediates. Any biological activity observed would be incidental and not the intended purpose.
ln Vivo
The compound itself is not typically evaluated for in vivo activity as it is a synthetic intermediate. Drug candidates synthesized from 4-Azepanone hydrochloride may be evaluated in animal models for various indications, but the biological activity is attributed to the final drug molecule rather than the intermediate. The compound's primary applications remain in chemical synthesis and medicinal chemistry research as a building block for heterocyclic drug discovery.
Enzyme Assay
Cell-free biochemical assays involving 4-Azepanone hydrochloride typically focus on its use as a synthetic reagent. In organic synthesis, the compound can be used as a building block for the preparation of various azepane derivatives. A standard protocol for reductive amination involves treating the ketone with an amine and a reducing agent (e.g., NaBH₃CN or NaBH(OAc)₃) in an appropriate solvent such as methanol or dichloroethane. The hydrochloride salt is typically neutralized with a base before reaction. Reactions are monitored by TLC and products are characterized by NMR and mass spectrometry. The compound's purity is verified by titration.
Cell Assay
Cell-based assays are not typically performed with 4-Azepanone hydrochloride as the compound is a chemical reagent rather than a drug candidate. If evaluating the biological activity of compounds synthesized from this intermediate, standard cell-based protocols would apply depending on the target indication. For example, cancer cell lines may be treated with the synthesized compound at various concentrations for 24-72 hours, and cell viability assessed by MTT or CellTiter-Glo assays. The intermediate itself may be used as a control.
Animal Protocol
In vivo studies are not typically conducted with 4-Azepanone hydrochloride itself. For drug candidates synthesized using this intermediate, standard in vivo efficacy studies involve rodent models of the target disease. A typical protocol includes oral or intravenous administration of the test compound at various doses, with monitoring of disease progression through appropriate endpoints. The azepanone core may influence the overall pharmacokinetic and pharmacodynamic profile of the final drug.
ADME/Pharmacokinetics
As a chemical reagent rather than a drug, comprehensive pharmacokinetic data for 4-Azepanone hydrochloride is not available. The compound's molecular weight is approximately 149.62 g/mol. The compound is a solid at room temperature. For drug molecules synthesized from this intermediate, ADME properties depend on the final structure. The azepanone core may confer moderate lipophilicity and hydrogen bonding capability. The hydrochloride salt form suggests good aqueous solubility.
Toxicity/Toxicokinetics
Toxicological data specific to 4-Azepanone hydrochloride is limited. As with all chemical reagents, standard laboratory safety precautions should be observed when handling this compound. The compound may cause irritation upon skin or eye contact. For drug candidates synthesized using this intermediate, comprehensive toxicological evaluation is required as part of the drug development process.
Additional Infomation
4-Azepanone hydrochloride is a research chemical and synthetic intermediate rather than an approved pharmaceutical agent. No clinical trials or regulatory approvals exist for this compound itself. It is commercially available from various chemical suppliers for research purposes only. The compound's primary value lies in its utility as a versatile building block in organic synthesis for the preparation of azepane-containing heterocyclic compounds and pharmaceutical intermediates. The seven-membered ring azepanone core is a useful scaffold in medicinal chemistry, enabling diverse functionalization for drug discovery.

  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
