N-(Cyclopent-1-Ene-1-Yl)Pyrrolidine stands out as a specialized chemical compound, often showing up as a stable, solid material in practical lab settings. Chemists recognize its structure by the linked cyclopent-1-ene ring fused to a pyrrolidine, marking it out from simpler amines and cyclic alkene compounds. Molecularly, it draws interest for its combination of saturated and unsaturated rings, which can influence how it reacts with acids and bases or participates in key organic transformations. Through years in the lab, I’ve seen how this type of compound attracts attention for synthesis projects, creating pathways to new materials and potential applications across multiple industries. Its versatility owes a lot to the unique interplay between its nitrogen-containing pyrrolidine ring and its unsaturated cyclopentene component, both crucial for researchers tuning reactivity and seeking targeted functionality.
N-(Cyclopent-1-Ene-1-Yl)Pyrrolidine carries the molecular formula C9H15N, with a molar mass that tips the scale at around 137.22 g/mol. Density measurements usually settle near 1.01 g/cm3; the specific value depends somewhat on temperature and form, but many lab reports confirm readings in this general neighborhood. With most samples, you’ll find it presents as a solid, often delivered as colorless to pale-yellow flakes or powder. Some suppliers might offer it in fine crystalline form, which pours much like sugar crystals and stores well in airtight containers. The compound rarely appears as a pearl or clear liquid at room temperature, but heated samples can show some transition, especially if purified for analytical runs. Laboratory handling always hinges on accurate density and melting data: correct labeling matters for safe storage, and mixing a misjudged density sample with solvents can trip up an experiment fast.
Safety data for N-(Cyclopent-1-Ene-1-Yl)Pyrrolidine should never get overlooked. Based on its chemical nature, there’s reason for caution about inhalation and contact; simple exposure causes irritation in some users, with a lingering amine odor that signals a need for good ventilation. Protective gloves, goggles, and access to eyewash always stay close by in my experience, since even brief skin exposure makes itself known with a sharp tingling or redness, similar to other cyclic amines. Handling raw materials involves watching for accidental spills, since powder can quickly go airborne, and any dust risks entering the eyes or mouth. Chemical supply sheets stress storage away from oxidizers, acids, and open flames, noting that pyrrolidine derivatives can react energetically with some lab staples. Though not classed as acutely toxic, most regulatory guides in the US and EU still list it as harmful and hazardous, demanding strict labeling and careful accounting for every gram used or discarded.
Structure sets the stage for almost any chemical’s use. In this case, the saturated pyrrolidine ring flanked by an unsaturated five-membered cyclopentene backbone creates a molecular scaffold fit for research into new pharmaceuticals, catalysts, and specialty polymers. Chemists tracking reaction pathways appreciate the balance between rigidity and flexibility; N-(Cyclopent-1-Ene-1-Yl)Pyrrolidine can serve as an intermediate, bridging the gap between basic starting materials and more advanced target molecules. The compound’s specific reactivity with electrophiles comes from its nitrogen atom, acting as a site for substitution and N-alkylation, while the double bond offers routes to cycloaddition and expansion reactions. Compared to off-the-shelf amines or alkenes, it builds a better foundation for custom synthesis. In practice, raw material grade often comes in purities over 98%, with trace water content held below 0.5%—critical for labs or industrial outfits demanding precision in reaction outcomes. Some suppliers ship it in sealed glass bottles of 25g, 100g, or as bulk material as required per order, taking care to eliminate light and moisture exposure.
Customs and regulatory professionals identify N-(Cyclopent-1-Ene-1-Yl)Pyrrolidine most easily by its Harmonized System (HS) Code 293339. This number, flagged in customs paperwork and safety data sheets, signals its place as a nitrogen-function organic compound under international commerce rules. Shipments crossing borders must arrive packaged with code labels, safety data, and clear origin documentation to keep imports above board. From experience tracking sample orders, getting this code right smooths downstream logistics—misfiled shipments can delay research projects or hold up manufacturing for weeks, especially with global customs crackdowns on chemicals flagged for dual-use or misclassification. Regulatory compliance also asks for up-to-date documentation on storage, shipping conditions, and disposal, underscoring the value of trusted suppliers who take chemical stewardship seriously. These steps help assure safe, legal movement of material from producer to lab.
Working with specialty chemicals calls out for respect—on the bench and through every stage from procurement to waste disposal. N-(Cyclopent-1-Ene-1-Yl)Pyrrolidine demands the same. The main challenge lies with balancing its desirable properties—solid state, stable density, targeted reactivity—against health and safety risks tied to its structure. Solutions start with detailed safety training, proper PPE use, and well-ventilated workspaces. Safe disposal methods, coordinated with local regulations, reduce environmental load and keep harmful residues out of municipal streams. In research, adopting greener protocols—using less solvent, recovering unused raw material, and exploring catalytic alternatives—delivers practical advances toward sustainability. Beyond the lab, policymakers and industry leaders can support responsible materials management by staying transparent about hazard classifications and ensuring accurate, clear labeling along the supply chain, from raw material to final formulation. These steps allow N-(Cyclopent-1-Ene-1-Yl)Pyrrolidine to play its role in chemistry’s future while keeping people and the environment secure.
