1-Dimethylamino-2,3-propanediol appears as a chemical compound belonging to the family of amino alcohols. This substance is recognized by its clear, sometimes slightly yellow liquid state at standard room temperature, although it may also crystallize in solid form under cooler conditions. The molecular formula is C5H13NO2, with a molecular weight clocking in at 119.16 g/mol. The presence of both hydroxyl and dimethylamino functional groups gives this material distinct chemical reactivity and versatility in synthesis, which matters in a number of industrial and research settings. Its density hovers around 1.05 g/cm³, which gives some clues about handling and storage in liquid or solid forms. The HS Code for 1-Dimethylamino-2,3-propanediol typically falls under 2922.19, placing it within the class of amino-alcohols for regulatory and logistics tracking.
Looking at the structure, 1-Dimethylamino-2,3-propanediol holds a straight three-carbon backbone, with hydroxyl groups on the second and third carbons. The dimethylamino group attaches to the first carbon. This arrangement generates both hydrophilic and hydrophobic interactions, making this compound soluble in water and a host of common solvents. Visual examinations usually mark it as colorless in its pure state, turning faintly yellow with age or exposure to contaminants. As a raw material, you might encounter it as flakes, solid, powder, or even as fine pearls, depending on manufacturing and shipping requirements. Moderate hygroscopic character means it draws in moisture from the air, so bulk quantities require airtight storage for both quality and safety. The melting point typically falls between 38 and 42°C, while boiling occurs around 218°C. This range means you can work with it in a variety of phases, especially if you're blending into a larger reaction mixture or dissolving it for solution preparation.
Depending on the supplier, 1-Dimethylamino-2,3-propanediol arrives in industrial drums or glass bottles ranging from small liter portions to large-scale containers over 200 liters. Purity grades usually exceed 98%, verified by common analytic techniques such as NMR and GC-MS. Specifications often note water content, color by Hazen scale, and residual solvent values — crucial for pharmaceutical and research contexts where impurities can shift a reaction or skew test results. Large-scale processes or custom formulations may require knowledge of bulk density, particle size for powder or pearls, or solubility in polar solvents. Safe handling gears toward chemical gloves, splash goggles, and lab coats, as human skin feels the material’s slight greasy or sticky touch. Ventilated working areas limit exposure to vapor or small spills, which can irritate mucous membranes or skin. For bulk operations, chemical-resistant pumps and closed systems prevent accidental release.
As with many synthetic organic chemicals, 1-Dimethylamino-2,3-propanediol draws attention for both its benefits and risk profile. Acute exposure may result in skin or eye irritation, especially for those not using basic PPE. Extensive inhalation rarely occurs due to its low vapor pressure, except in heated or misted states; ingestion risks prompt the standard chemical safety protocols. International material safety sheets rank it as harmful if ingested or absorbed, yet not carcinogenic or mutagenic based on available research. Waste handling follows standard organic disposal, avoiding releases into sewers or watercourses. Environmental persistence remains low to moderate due to relative biodegradability, but large accidental spills would still threaten aquatic life and water quality. Fire risk is limited, yet elevated temperatures can produce toxic vapor so containment features and firefighting agents tailored for organic solvents should remain nearby. Emergency procedures include eyewash stations and immediate decontamination for exposed staff, according to occupational guidance.
Chemical manufacturers and R&D labs value 1-Dimethylamino-2,3-propanediol as a versatile intermediate, especially in the synthesis of pharmaceuticals and surfactants. Its bifunctional structure enables coupling with acids or activated halides, making it a key building block in custom or large-scale reactions. In scenarios I’ve seen, researchers favor this material for selective functionalization, employing rugged flasks and jacketed reactors to control both temperature and mix quality. Demands for reliable supply underscore the importance of tracking specifications at each delivery, along with regularly checking for off-odors or discoloration, which might signify either contamination or age-related decomposition. As a solid or powder, its fine grains flow easily from containers but can cake if exposed to air too long; manufacturers often nitrogen-purge drums to limit these effects. In solution, 1-Dimethylamino-2,3-propanediol integrates smoothly with alcohols or glycols, opening doors for a spectrum of downstream processing routes.
Management of 1-Dimethylamino-2,3-propanediol supply chains in today’s market means integrating tighter quality control, improved worker training, and more robust environmental safety programs. Suppliers proactive about sharing updated certificates of analysis, batch-specific data, and storage guidance help firms avoid unplanned downtime and reduce risk of product loss. Addressing the environmental side, some producers are investigating greener synthesis pathways — using water-based chemistry instead of chlorinated solvents — to shrink the overall impact. In workplaces, regular worker briefings on handling protocol, real-time safety monitoring, and escalation procedures for chemical spills prevent harm to both person and property. Digital inventory management flags expiring or at-risk lots before use, and modular lab setups streamline cleaning and rapid isolation when problems arise. Seen through the lens of direct experience, these efforts yield safer work environments, consistent product quality, and a lighter environmental footprint.
