Industrial Applications of BOC-ALA-OTBU
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Synthesis intermediate for peptide-based therapeutics and active pharmaceutical ingredients (APIs) | Used as a protected form of L-alanine in solid-phase peptide synthesis (SPPS) or solution-phase synthesis; BOC and tert-butyl ester groups are cleaved via acidolysis (e.g., trifluoroacetic acid) to enable selective reactions at the amino and carboxyl groups |
| Organic Synthesis | Chiral amino acid derivative building block | Applied in asymmetric synthesis and preparation of chiral ligands or catalysts; specific functional groups are introduced via transesterification, amidation, reduction, and related reactions |
| Biochemical Research | Labeling or modification precursor for protein structure and function studies | Provides controlled reactivity in peptide chain elongation, isotopic labeling (e.g., 13C/15N-labeled alanine residues), and fluorescent probe conjugation |
Manufacturing Quality Control of BOC-ALA-OTBU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection at multiple wavelengths. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol solvent system. |
| Optical Rotation | [alpha]D Measurement | Determination of specific rotation using a polarimeter at 20 C with sodium D-line (589 nm) light. |
| Heavy Metals | ICP-MS | Quantification of trace metal impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after anion exchange. |
| Residual Tert-Butyl Alcohol | GC-FID | Direct headspace or liquid-injection GC-FID analysis targeting tert-butyl alcohol as a process-related impurity. |
| Residual BOC Anhydride | HPLC-UV | Derivatization-free HPLC-UV detection of di-tert-butyl dicarbonate based on its UV absorbance. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
