Industrial Applications of Methyl DL-2-aminopropanoate hydrochloride
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral synthesis intermediate for the preparation of antibiotics and amino acid–based drugs | Prepared via esterification of DL-alanine with methanol under hydrochloric acid catalysis |
| Chemical Synthesis | Amino-protecting group or chiral auxiliary in organic synthesis | Esterified with alcohols under acidic conditions, followed by purification to yield the hydrochloride salt |
| Pesticides | Synthesis of biologically active pesticide molecules containing the alanine moiety | Used as a precursor in condensation or acylation reactions to construct the active ingredient backbone |
Manufacturing Quality Control of Methyl DL-2-aminopropanoate hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Alanine Methyl Ester Hydrochloride) | Acid-Base Titration | Quantifies active compound by titration with standardized NaOH using bromocresol green indicator; endpoint corresponds to neutralization of HCl salt. |
| Water Content | Karl Fischer Titration | Measures water via iodine-sulfur dioxide reaction in methanol-based reagent; stoichiometric determination of water content. |
| Specific Optical Rotation | Polarimetry | Determines optical activity using sodium D-line light; indicates enantiomeric composition and purity of chiral center. |
| Residual Solvents (Methanol, Ethyl Acetate) | Gas Chromatography (GC) | Separates and quantifies volatile solvents using flame ionization detection (FID) against calibrated standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion; detects trace metals at sub-ppb levels via mass spectrometric ion counting. |
| Chloride Content | Potentiometric Titration | Measures Cl- ions using silver nitrate titrant and silver/silver chloride electrode; endpoint detected by potential inflection. |
| Related Substances (Impurities) | HPLC with UV Detection | Separates and quantifies organic impurities (e.g., DL-alanine, methyl ester hydrolysis products) using reversed-phase C18 column and UV absorbance at 205 nm. |
| pH (1% aqueous solution) | pH Meter Measurement | Determines acidity of aqueous solution using calibrated glass electrode; reflects residual acidity and salt stability. |
| Appearance | Visual Inspection | Assesses physical state (white to off-white crystalline powder), color, and absence of visible foreign particles under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition; verifies identity and crystallinity by comparison to reference standard. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying at 105 C for 2 h; indicates volatile content including residual solvents and moisture. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects aerobic microorganisms and absence of specified pathogens (e.g., E. coli, S. aureus) using nutrient agar and selective media. |
