Industrial Applications of HOAt
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Condensing agent in peptide synthesis to enhance coupling efficiency and suppress racemization | Used in solid-phase peptide synthesis (SPPS) in combination with carbodiimide reagents (e.g., DIC, DCC) to activate carboxyl groups and form active esters |
| Organic Synthesis | Catalyst or auxiliary for constructing amide, ester, and other functional groups | Promotes condensation reactions between carboxylic acids and amines/alcohols under mild conditions; commonly applied in late-stage modification of complex molecules |
| Materials Science | Crosslinking aid or modifying additive in functional polymer synthesis | Participates in polymerization reactions (e.g., polyurethane, polyamide) as a comonomer or initiation aid to improve thermal stability of materials |
Manufacturing Quality Control of HOAt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~210–230 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally similar impurities (e.g., 7-aza-benzotriazole, hydroxylamine derivatives) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., ethyl acetate, toluene, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, Ni) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (500–600 °C) and weighing of residual non-volatile matter. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance & Color | Visual Inspection / Hazen/APHA Color Scale | Subjective assessment of physical state (crystalline powder) and color intensity compared to platinum-cobalt standards. |
| pH (1% w/v aqueous suspension) | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using a calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution based on angular scattering pattern of laser light passing through dispersed sample. |
| Organic Volatile Impurities (e.g., N-nitroso compounds) | GC-MS | Targeted screening and quantification of genotoxic impurities using gas chromatography coupled with mass spectrometric detection. |
| Chloride Content | Ion Chromatography (IC) | Quantification of chloride anion after sample dissolution and separation on an anion-exchange column with conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after ignition with sulfuric acid treatment, per USP <281>. |
