1-Hexanesulfonic acid sodium salt belongs to the class of chemical compounds known as alkane sulfonates. It carries the molecular formula C6H13NaO3S and a molar mass of about 204.22 g/mol. This compound typically comes as a white to off-white powder, though various suppliers might supply it in flakes, crystals, or as a fine, free-flowing solid. Its chemical structure combines a hexane chain with a sulfonic acid group, neutralized by a sodium ion. The HS Code commonly used for this substance in international trade is 2921.19, which relates to sulfonic acids and their salts. My experience working in a quality lab taught me that the purity and particle shape of these organic salts influence how well they perform in experiments or processes, because impurities and inconsistent morphology can create frustrating results.
1-Hexanesulfonic acid sodium salt displays high water solubility, due to the polar sulfonic group and ionic nature. Its density ranges from 1.3 to 1.6 g/cm3, depending on crystalline form and moisture content. The solid can appear as fine powder, small pearls, or even granular flakes, but in liquid applications, people often prepare concentrated aqueous solutions by dissolving the raw solid. The substance shows low volatility and melts above 300°C, though exact measurement depends on both hydration state and purity. In practice, I've seen the choice between powder or flakes made simply on how easily the material pours from a scoop or dissolves—in industrial settings, time lost fiddling with a slow-dissolving solid can translate into real dollars. It’s non-volatile, with negligible odor, making handling straightforward compared to more volatile sulfonic acids.
In laboratory settings, 1-hexanesulfonic acid sodium salt often plays a key role as an ion-pairing reagent in high-performance liquid chromatography (HPLC). It helps separate molecules that otherwise elude traditional methods, because it forms reversible complexes with basic compounds and increases their retention on column packings. Many analytical chemists favor the hexane length for balancing lipophilicity and solubility. In manufacturing, the compound finds occasional use as a surfactant or intermediate, exploiting the sulfonate’s detergent qualities. Some technical-grade batches support textile finishing or specialty syntheses, where its salt form remains preferred for ease of handling, stability, and process control.
The backbone of 1-hexanesulfonic acid sodium salt consists of a linear six-carbon chain attached to a sulfonic acid group, which sodium neutralizes. The formula C6H13NaO3S maps out straightforwardly: CH3(CH2)5SO3Na. In bulk, this structure creates a material with low reactivity toward mild acids and alkalis, but the sulfonate will hydrolyze in highly acidic media. Experience teaches that storing sulfonate salts in air-tight containers reduces moisture uptake and clumping, as these salts often pull water out of humid air and turn sticky fast. For those in the warehouse or chemistry storeroom, robust packaging—such as double-lined drums—minimizes spills and caking.
Manufacturers specify 1-hexanesulfonic acid sodium salt by purity, usually above 98% for analytical use, with moisture and heavy metals screened as trace contaminants. Particle size affects how quickly the salt dissolves or blends in solutions, with finer powders dissolving faster but potentially more prone to dust formation during weighing. Density typically remains within a narrow range, but customers sometimes request certificate of analysis data showing measured property values such as melting point, solubility, and assay. Having spent time preparing solutions, I’ve learned to rely on trusted suppliers and up-to-date COAs, since low-grade material can introduce ionic contamination, impacting downstream work or causing regulatory headaches.
Classified as a chemical, 1-hexanesulfonic acid sodium salt presents mild hazard primarily in eye or skin exposures, where concentrated powder causes irritation. Good safety protocol includes gloves and safety goggles, with lab ventilation for measuring powders. Unlike many sulfonic acids, its sodium salt form remains stable and non-flammable, which greatly reduces workplace risks. Nonetheless, inhaling fine particulate can cause respiratory hassle, especially for workers with sensitivities. Accidental spills need prompt cleaning with water, since dry residues absorb moisture and become slippery, posing fall risks even in routine use. Chemical disposal follows local regulations, but sodium alkane sulfonates typically break down into harmless products with proper wastewater treatment, reducing long-term hazards. It carries no major classification as an environmental toxin, so releases in trace quantities rarely raise alarm among regulators or auditors.
For companies and research labs sourcing 1-hexanesulfonic acid sodium salt as a raw material, insight into its structure, properties, and hazards enables smarter procurement and safer workplaces. Relying on detailed material data, up-to-date specifications, and trustworthy suppliers matters more than ever for compliance and product quality. Chemists, handlers, and purchasing managers benefit from training on safe handling, responsible storage, and routine review of packing condition and labeling. Recognizing the balance between purity, particle size, and form—flakes, powder, pearls, or solution—makes day-to-day work smoother, keeping projects on schedule and benchmarks achievable. Integration of strong chemical safety programs, together with careful logistics, supports ongoing operations with minimal disruption.
