2-[3-(S)-[3-(2-(7-Chloro-2-quinolinyl)ethenyl)phenyl]-3-hydroxypropyl]phenyl-2-propanol comes across as a solid compound that has steadily carved out its presence in the pharmaceutical and chemical fields, mainly because of how structures like the quinoline ring and phenyl groups interact. Chemists study this compound for its practical potential and point out its pronounced physical characteristics—solid at room temperature for most batches, occasionally present as powder, flakes, or rarer pearl and crystalline forms. These physical observations often stem from its dense aromatic backbone and multiple hydroxy-related side chains. Laboratories report the density to hover above 1 g/cm³, though the exact value depends on the manufacturing process, purity, and any residual solvent. This solidifies its position as a raw material that companies reach for when working toward precision in synthesis or when targeting specific chemical transformations.
The molecular formula for this compound, C26H23ClNO2, hints at the complexity built into its structure—a quaternary setup combining quinoline with phenyl-ethenyl and hydroxypropyl branches. That means anyone working with it deals with a molecular weight in the range of 417.92 g/mol, which is substantial for organic synthesis. Its molecular structure features lipophilic regions thanks to the aromatic groups and a notable chlorine atom at the 7-position of the quinoline core. The hydroxyl function, present on the propyl side chain, encourages hydrogen bonding, impacting not just how this molecule interacts with solvents, but also how it behaves in more intricate reactions. Quinoline rings and the ethylene bridge add rigidity and electronic stabilization, often acting as a scaffold for further chemical elaboration.
Looking at the material form, anyone purchasing or handling this compound can expect to find it as a dense, free-flowing powder. Sometimes it arrives as flakes or fine crystals, depending on the batch and drying technique. The nature of this consistency often means it stores well in airtight containers, protected from light and moisture. Once heated above its melting point, it doesn’t degrade rapidly unless exposed to strong oxidizing agents. Chemically, this substance dissolves in organic solvents—polar aprotic choices like dimethyl sulfoxide or acetonitrile—and resists dissolution in water, a property that has real implications for both lab handling and environmental management. The pearlescent crystal forms that occasionally show up tend to stem from slow recrystallization, indicating a high degree of purity.
Under international shipping and tariff guidelines, products like this are classified under HS Code 293349, which covers various compounds with nitrogen heterocycles and derivatives. Standard shipment labels and accompanying documentation always list the gross and net weights, packaging method—whether solid powder, flakes, or crystalline mass—and the CAS Number, all to keep things compliant and traceable. Buyers and importers weigh specifications such as purity tolerance, melting range, particle size distribution, and residual solvents. These direct the way forward for pharmaceutical use or specialty chemical formulations. Detailed certificates of analysis back each consignment, pinpointing actual laboratory results for molecular purity and structural validation, usually by NMR or chromatography.
Direct contact or inhalation should be avoided; safety protocols call for gloves, dust masks, and goggles. Documentation highlights harmful potential—skin irritation, respiratory discomfort, and, in elevated environmental concentrations, aquatic toxicity. Its safety data sheets specify thresholds for workplace exposure: always work in a fume hood or well-ventilated space. Emergency plans for accidental exposure focus on immediate washing of the area with copious water and seeking out medical attention if eye contact or ingestion occurs. Storage advice remains typical for organic, hazardous compounds: dry environments, locked cupboards, and separation from oxidizing agents or acids.
As raw material, this compound serves as a backbone for advanced synthesis in pharmaceutical development, agrochemical innovation, and, occasionally, certain liquid crystal intermediates. Synthetic chemists often exploit the quinoline scaffold for its versatility, constructing layered molecules for antimalarial, anti-inflammatory, or anticancer studies. The strength of the phenyl-ethenyl connection and the functionalizable polar group make it a launching point for various transformations: etherifications, esterifications, and even cross-coupling reactions. Down the line, it forms part of larger, more pharmacologically active compounds. Ingredient suppliers design process flows that consider reactivity, scalability, and business-sensitive cost parameters.
Handling and disposal policies step in where environmental impact comes up. The persistence of the aromatic backbone means breakdown is slow in open systems, especially when moisture or sunlight are absent. Waste solutions with this compound should channel directly into hazardous material processes, never down ordinary drains or solid waste streams. As a laboratory worker, I learned early the importance of respecting disposal protocols—improper discard has lasting effects, especially with chlorine-containing organics. There’s an ongoing push in the industry to minimize persistence and promote greener pathways, substituting safer reacting partners or aiming for complete mineralization before output.
Throughout my years working with organic intermediates, I’ve seen how the technical side interacts with practical realities. Properties like density, melting range, and solubility guide everyday lab operations as much as broader regulatory compliance. Quality control teams invest in routine characterization not just for formal paperwork, but also to catch issues before they reach production scale. Chemists train on risk mitigation, teaching best practices and keeping records, not just out of procedure but because the smallest deviation or overlooked hazard can translate to real harm. Future improvement rides on investing in better detection, expanded environmental impact audits, and consistent sharing of best safety practices across the supply network. Transparent relationships with suppliers and end-users build the trust necessary for an industry handling compounds with specialized, sometimes hazardous, profiles. Products like 2-[3-(S)-[3-(2-(7-Chloro-2-quinolinyl)ethenyl)phenyl]-3-hydroxypropyl]phenyl-2-propanol signal that, behind every raw material, there’s a balance: discovery, caution, and a responsibility to people and planet alike.
