Industrial Applications of AC-GLU(OTBU)-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used in the synthesis of L-glutamic acid derivative drugs, such as N-acetyl-L-glutamate (NAG), a key active pharmaceutical ingredient in treatments for urea cycle disorders (e.g., Carbaglu®) | Serves as a protected glutamic acid building block in solid-phase peptide synthesis (SPPS) or solution-phase synthesis; the tert-butyl ester group is cleaved under acidic conditions (e.g., trifluoroacetic acid/TFA) prior to coupling reactions |
| Organic Synthesis | Employed as a chiral amino acid protecting reagent for constructing glutamic acid-containing peptides, enzyme inhibitors, and targeted molecular probes | Undergoes amidation or transesterification using coupling systems such as DCC/HOBt or EDC/HOAt under mild basic conditions (e.g., DIPEA in DCM) |
Manufacturing Quality Control of AC-GLU(OTBU)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., tert-butanol, DCM, DMF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water via iodine-sulfur dioxide reaction in anhydrous pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Ni after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity-based detection of chloride ions in aqueous extract after sample dissolution and filtration. |
| Sulfate Impurity | Ion Chromatography | Separation and conductivity-based detection of sulfate ions in aqueous extract following sample preparation. |
| Optical Rotation | [alpha]D Measurement | Determination of specific rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (700-800 C) and weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size distribution by measuring angular scattering intensity of laser light. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) by membrane filtration and culture. |
