| Industry | Application | Process |
|---|---|---|
| Nutritional Supplements | NAD+ precursor for enhancing cellular energy metabolism | Formulated as oral supplements |
| Pharmaceutical R&D | Research on anti-aging and neuroprotection | Administration in preclinical and clinical trials |
| Biotechnology | Additive for cell culture | Added to culture media to support cell viability |
| Functional Foods | Functional ingredient for metabolic enhancement and anti-fatigue effects | Formulated into functional beverages or foods |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies NR concentration by UV absorption at 260 nm using a reversed-phase C18 column and external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., nicotinamide, ribose, NR degradation products) via gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (Pb, Cd, As, Hg, Ni) by inductively coupled plasma mass spectrometry after acid digestion. |
| Water Content | Karl Fischer Titration | Quantifies total water by coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Optical Rotation | [alpha]D Measurement | Measures specific optical rotation at 589 nm using a polarimeter to confirm chiral integrity and absence of racemization. |
| pH of Solution | Potentiometric pH Measurement | Determines pH of a defined aqueous solution (e.g., 1% w/v) using calibrated glass electrode and pH meter. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration (700-800 C) followed by weight determination of residual residue. |
| Microbial Limits | Membrane Filtration / Plate Count | Assesses total aerobic microbial count and absence of specified pathogens (E. coli, Salmonella, S. aureus) per USP <61> and <62>. |
| Particle Size Distribution | Laser Diffraction | Determines D10, D50, D90 values by analyzing light scattering patterns of dispersed powder in air or liquid medium. |
| Melting Point | Capillary Melting Point Apparatus | Identifies characteristic melting range using controlled heating and visual observation of phase transition in capillary tube. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measures weight loss under controlled heating (e.g., 105 C, 2 h) to quantify volatile components excluding water (e.g., solvates, low-MW volatiles). |
