Industrial Applications of S-2--Bromobutyric acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral synthetic intermediate for β-amino acid–based drug synthesis | Prepared via nucleophilic substitution of S-2-hydroxybutyric acid with a brominating agent (e.g., PBr₃ or SOBr₂) |
| Pesticides | Precursor for synthesizing chiral brominated pesticide molecules | Reaction of an S-2-butanol derivative with hydrogen bromide or phosphorus bromide under low-temperature conditions |
| Chemical Synthesis | Chiral building block for constructing optically active compounds | S-configuration obtained via asymmetric synthesis or chiral resolution, followed by esterification or acylation for derivatization in complex molecule construction |
Manufacturing Quality Control of S-2--Bromobutyric acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (S-2-bromobutyric acid content) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Optical Purity (Enantiomeric Excess) | Chiral Gas Chromatography (cGC) | Separation and quantification of S- and R-enantiomers using a chiral stationary phase; enantiomeric excess calculated from peak areas. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Residual Solvents (e.g., hexane, ethyl acetate) | Headspace Gas Chromatography (HS-GC) | Volatile solvents are equilibrated in headspace vial, then injected and quantified via GC-FID using external calibration. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Sample digested in nitric acid; elements ionized in plasma and detected by mass-to-charge ratio with ultra-trace sensitivity. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on anion-exchange column; chloride quantified by conductivity response relative to calibration standards. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of carboxylic acid groups with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated at 700-800 C in platinum crucible; inorganic residue weighed after cooling in desiccator. |
| Appearance (Color & Clarity) | Visual Inspection Against Standard Solutions | Comparison of sample solution (in specified solvent, e.g., methanol) with APHA or Hazen color standards under controlled lighting. |
| Specific Optical Rotation | [a]D Measurement Using Polarimeter | Measurement of rotation angle of plane-polarized light passing through a solution; specific rotation calculated from concentration, path length, and observed angle. |
| Related Substances (Impurity Profile) | High Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column; impurities detected at 210 nm and quantified using external standard or area normalization. |
| pH of Aqueous Solution (1% w/v) | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode in aqueous suspension or solution prepared per USP/EP guidelines. |
