Cyclopropyl-1

Updated: 2026-08-21

Overview

Cyclopropyl-1 is a simple hydrocarbon with a three-membered ring structure. It is widely used in the chemical industry due to its reactivity and versatility. The compound is a key intermediate in the synthesis of various pharmaceuticals and agrochemicals. Cyclopropyl-1 is known for its unique ring strain, which makes it highly reactive. This property is leveraged in organic synthesis to create complex molecules. Despite its usefulness, it requires careful handling due to its flammability and volatility.

Physical and Chemical Properties

Cyclopropyl-1 is a colorless gas or liquid at room temperature, depending on pressure. It has a low boiling point and density, making it highly volatile. The compound is slightly soluble in water but mixes well with organic solvents like ethanol and ether. Chemically, cyclopropyl-1 is highly reactive due to the strain in its three-membered ring. This strain makes it prone to ring-opening reactions, which are useful in synthetic chemistry. Its flammability requires strict safety measures during handling and storage.

B2B Procurement Guide

When procuring cyclopropyl-1, verify the supplier's compliance with safety and quality standards. Request material safety data sheets (MSDS) and certificates of analysis (CoA) to ensure product purity. Bulk purchases may offer cost advantages, but storage capacity must be considered. It is advisable to establish long-term relationships with reliable suppliers to ensure consistent quality. Compare prices from multiple vendors, but prioritize safety and regulatory compliance over cost. Always confirm delivery and handling protocols before placing an order.
