Industrial Applications of 1,4-Butane-disulfonate
| Industry | Application | Process |
|---|---|---|
| Electroplating | Added to copper electroplating baths to improve deposit uniformity and brightness | Added to acidic sulfate copper plating baths at typical concentrations of 1–10 mg/L; acts synergistically with chloride ions to refine grain structure |
| Organic Synthesis | Used as a multifunctional sulfonating agent and crosslinker | Participates in condensation reactions to prepare sulfonic acid-functionalized polymers; undergoes substitution or condensation polymerization with diols, diamines, and other bifunctional compounds under alkaline conditions |
| Water Treatment | Component of scale and dispersion inhibitors to suppress calcium carbonate and calcium sulfate scaling | Formulated into multi-component copolymer systems (e.g., acrylic acid/sulfonic acid copolymers); functions via combined chelation and crystal lattice distortion mechanisms |
| Pharmaceutical Intermediates | Key side-chain precursor in the synthesis of the antithrombotic drug tirofiban | Introduced as a sulfonic acid-containing butanediamine derivative via multi-step reactions including esterification, amidation, and chiral resolution |
Manufacturing Quality Control of 1,4-Butane-disulfonate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Take an appropriate amount of sample and place it on a white background. Observe its color, state, and presence of visible impurities under natural light or standard illumination. It should be a white crystalline powder or a colorless to slightly yellow solid. |
| Identification | Infrared Spectroscopy (IR) Nuclear Magnetic Resonance (¹H NMR) |
Compare the characteristic absorption peaks of the sample with the standard spectrum using IR; or determine the chemical shift and coupling constants of hydrogen atoms by ¹H NMR to confirm whether the molecular structure matches that of 1,4-butanedisulfonic acid. |
| Content Determination | Acid-Base Titration High-Performance Liquid Chromatography (HPLC) |
Acid-Base Titration: Titrate the total acidity of the sample with a standard sodium hydroxide solution, using phenolphthalein as an indicator, and calculate the content of the main component. HPLC: Use a reversed-phase C18 column, with a phosphate buffer-methanol mobile phase, and detect at 210 nm with a UV detector, using an external standard method for quantification. |
| pH Value | pH Meter Method | Prepare a solution of a certain concentration (e.g., 1% w/v) and measure its pH value using a calibrated pH meter. The value should be within the specified range (usually 1.0–3.0). |
| Drying Loss | Thermogravimetric Analysis (TGA) or Drying to Constant Weight | Dry the sample at 105°C until constant weight is achieved, and calculate the percentage of mass loss to evaluate the moisture and volatile substance content. |
| Residue on Ignition | Ignition Method (as per Pharmacopoeia General Rules) | Ignite the sample at high temperature (usually 700–800°C), then weigh the residual inorganic matter to assess the total amount of inorganic impurities. |
| Heavy Metals | Sodium Sulfacetamide Method (Colorimetry) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Sodium Sulfacetamide Method: Generate a colored precipitate by reacting with sodium sulfacetamide under acidic conditions, and compare it with a standard lead solution; ICP-MS: Determine the content of specific heavy metal elements such as lead, arsenic, cadmium, and mercury with high sensitivity. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use a gradient elution HPLC system to separate and detect possible synthetic by-products or degradation impurities (such as monosulfonic acid derivatives or unreacted raw materials). Limit control is performed using area normalization or the main component self-control method with correction factors. |
| Moisture | Karl Fischer Titration | Quantitatively react the sample's water with Karl Fischer reagent, and accurately determine the moisture content using coulometry or volumetry. |
