Industrial Applications of 2-C-Methyl-D-ribono-1,4-lactone
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Synthesis | Intermediate for vitamin C (ascorbic acid) synthesis, used to produce L-ascorbic acid | Catalytic hydrogenation or reduction converts 2-C-methyl-D-ribonic acid 1,4-lactone into an L-ascorbic acid precursor, followed by oxidation and cyclization to yield vitamin C |
| Biochemical Research | Substrate or reference standard for studying enzyme activity related to carbohydrate metabolism | Serves as a model ribose-derived compound in in vitro enzymatic assays to investigate catalytic mechanisms of glycosyltransferases, isomerases, and related enzymes |
| Chemical Reagent | Starting material for synthesizing other chiral organic compounds | Undergoes multi-step transformations—including ring opening and functional group modifications (e.g., hydroxyl protection, oxidation, reduction)—to construct complex molecules with defined stereochemistry |
| Food Additive Development | Potential precursor for functional food ingredients, used in antioxidant product development | Subjected to biotransformation or chemical modification under mild conditions to enhance stability and bioavailability in food systems |
| Biomedical Materials | Monomer for preparing biodegradable polymeric materials | Participates in polymerization reactions (e.g., condensation or ring-opening polymerization) to form biocompatible polymers via copolymerization with other monomers |
Manufacturing Quality Control of 2-C-Methyl-D-ribono-1,4-lactone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and detection of impurities using HPLC coupled with diode array detection; identification and quantification based on retention time and spectral match. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and pyridine in methanol to determine water content by stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals | ICP-OES | Quantitative multi-element analysis after acid digestion, measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on ion-exchange column with conductivity detection; chloride quantified against calibration standards. |
| Sulfate Impurity | Ion Chromatography | Same as chloride but optimized for sulfate elution and detection using suppressed conductivity. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through solution; used to confirm stereochemical integrity. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, indicating purity and identity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement using calibrated glass electrode in 1% w/v aqueous solution at 25 C. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured after drying at 105 C for 2 hours under vacuum or nitrogen atmosphere. |
| Microbial Limits | Membrane Filtration | Sample filtration followed by culture on soybean-casein digest agar and sabouraud dextrose agar; enumeration of aerobic bacteria and fungi. |
