Chemical Structure

Basic Info
The chemical formula of Cyclopentanethiol, C 5 H 1, is a sulfur organic compound composed of a five-membered cyclopentane structure and a thiol substituent (-SH). It is a colorless or pale yellow liquid, with a strong thiol odor. It boils at 138-140 degrees C and is insoluble in water, but easily soluble when dissolved in organic solvents. The Cyclopentanethiol thiol group is highly reactive and can be used in nucleophilic, oxidation and alkylation reactions. It is used in organic synthesis as a thiol intermediary or to modify the surface functional groups of materials.
Cyclopentanethiol has other potential uses in medicine and pesticides. For example, it can be used as a pre-cursor for the synthesizing of heterocyclic compounds containing sulfur. The volatile nature of the compound and its irritating smell require that it be ventilated and protected during experiments. Cyclopentanethiol can also be used as a catalytic ligand due to its coordination ability. To prevent oxidation or the formation of disulfides, you should avoid exposure to light when storing.

Product Packaging

Cyclopentanethiol, with the chemical formula C ₅ H NINE SH, is a natural substance having thiol (- SH) useful groups. It has a common thiol smell, strong and pungent. It is a framework developed by replacing a hydrogen on cyclopentane with a thiol team (- SH).
1. Organic synthesis intermediates
Cyclopentanethiol is frequently utilized in organic synthesis, specifically in synthesis responses that call for the intro of thiol groups. It can serve as:
Thiolation reagent: used to introduce – SH teams into other molecules.
Constructing precursors for sulfur-containing natural compounds, such as thiazole and thiophene substances.
Made use of for thiol protection or deprotection reactions.
2. Drug growth and chemical modification
In medicinal chemistry, cyclopentanethiol can be utilized as an architectural alteration reagent for certain candidate medications, especially:
Presenting hydrophobic thiol groups to change the lipid solubility and bioavailability of compounds.
Creating sulfur bonds or metal complicateds for targeted medication style.
3. Products Scientific Research and Polymer Scientific Research
Cyclopentanethiol can be made use of for functionalized polymer products:
Surface modifiers: For instance, made use of to change nanoparticles or steel surfaces (such as gold nanoparticles) to create steady gold sulfur bonds (Au-S).
As a thiol particle with moderate chain length in self-assembled monolayers (SAMs), it is made use of to regulate surface area buildings.
4. Analytical chemistry and steel complexing representatives
Cyclopentanethiol can develop complicateds with some heavy metal ions because of its active thiol team, which has a specific steel capture capability.
Can be utilized as a logical reagent for finding or enriching particular metal aspects.
5. Odor regulation and olfactory research study
Although Cyclopentanethiol has a solid smell and is not suitable for direct usage as a seasoning, it:
It is utilized as a strong sulfur referral compound in some smell model researches.
In study on sting agents or smell masking, it may be made use of to check the efficiency of masking representatives.
6. Potential organic activity research
Compounds having thiol groups usually have:
Antioxidant capacity lowers oxidative damages by reacting with cost-free radicals.
Some sulfur-containing compounds additionally have the possibility for antibacterial or anti-tumor task, and Cyclopentanethiol as one of the design structures may be utilized for artificial insemination activity screening.
