Industrial Applications of Sodium cyanoborohydride
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Reductive amination of amine compounds | Reduction of imine or iminium ion intermediates to the corresponding amines using sodium cyanoborohydride under mildly acidic conditions (e.g., pH 3–4) |
| Pharmaceutical Industry | Selective reduction of aldehydes or ketones | Preferential reduction of aldehydes or ketones to alcohols under controlled pH conditions, while preserving functional groups susceptible to reduction by conventional borohydrides (e.g., esters, nitro groups) |
| Chemical & Agrochemical Manufacturing | Reductive alkylation reactions | Serving as a reducing agent in condensation reactions between aldehydes or ketones and amines to yield alkylated amine products |
| Organic Synthesis | Reductive dehalogenation of carbonyl compounds | Dehalogenation of halo-ketones or halo-aldehydes to the corresponding ketones or aldehydes in acidic media |
| Laboratory Reagent | Metal ion analysis | Reduction and recovery of noble metal ions, such as gold and silver |
| Organic Synthesis | Reductive desulfurization | Cleavage of carbon–sulfur bonds as a reducing agent in desulfurization reactions |
Manufacturing Quality Control of Sodium cyanoborohydride
| Test Item | Common Testing Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Place an appropriate amount of sample on a white background and observe its color, physical state, and presence of foreign particles under natural light or standard illumination. Sodium cyanoborohydride should appear as a white to off-white crystalline powder, free from visible impurities. |
| Identification | Infrared Spectroscopy (IR) | Prepare a pellet (e.g., KBr pellet), measure the infrared absorption spectrum, and compare it with the reference spectrum to confirm consistency of characteristic absorption peaks (such as vibrational peaks of functional groups like B–H and C≡N). |
| Assay | Acid-Base Titration (Iodometric method or hydrolysis followed by titration) | Hydrolyze the sample under controlled conditions to generate boric acid and cyanide, or allow direct reaction with iodine. Titrate the remaining reductant using standardized iodine solution, and calculate the sodium cyanoborohydride content based on iodine consumption. Alternatively, non-aqueous titration may be performed in a suitable solvent. |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v), and measure pH using a calibrated pH meter. The pH typically should fall within the range of 8.0–10.0 (specific limits depend on pharmacopoeial or company standards). |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Weigh the sample and dry it at a specified temperature (e.g., 60–80°C) for a defined period until constant weight is achieved. Calculate the percentage weight loss to assess moisture and volatile impurity content. |
| Sulfated Ash / Residue on Ignition | High-Temperature Ignition Method | Ignite the sample at high temperature (typically 700–800°C) until constant weight is reached, then determine the mass of residual inorganic material to control inorganic salt impurities. |
| Heavy Metals | Thioacetamide Method (Colorimetry) or Atomic Absorption Spectroscopy (AAS) | Treat the sample according to pharmacopoeial procedures, add thioacetamide for color development, and compare with a standard lead solution; or use AAS to directly determine levels of specific heavy metals such as lead, arsenic, and mercury. |
| Residual Cyanide | Spectrophotometry (Pyridine-Barbituric Acid Method) or Ion Chromatography | Treat the sample to release cyanide ions, which react with reagents to form colored compounds measured at a specific wavelength; or separate and quantify cyanide ions using ion chromatography to control toxic impurities. |
| Boron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) or Titration | Determine total boron content using ICP-OES to verify consistency with the main component; or measure the amount of boric acid produced after hydrolysis via acid-base titration, and calculate boron content indirectly. |
