Melatonin 99% Powder Pharmaceutical Intermediate China Manufacturer Sleeping-Aid
If you work in supplements or pharma intermediates, you already know the market is leaning hard into clean-label actives with tight specs. To be honest, Melatonin 99% Powder Pharmaceutical Intermediate China Manufacturer Sleeping-Aid hits that sweet spot: consistent assay, transparent testing, and flexible formats for modern delivery systems (gummies, sticks, microencapsulated blends—you name it). I visited the facility once near Zhengding, and it felt meticulous in the best possible way.
What it is and why it matters
Melatonin (CAS 73-31-4) is a neurohormone from the pineal gland that regulates circadian rhythm. In industry speak: a high-purity functional ingredient that supports sleep-related formulations. This lot is Non-GMO, BSE/TSE free, non-irradiated, and allergen free. Many customers say the flow and compressibility are surprisingly good for a 99% grade—no small thing when you’re running fast tablet tooling.
Core specifications
| Assay (HPLC) | ≥99.0% (typical ≈99.3% in recent COAs) |
| Appearance | White to off-white crystalline powder |
| Particle size | 80–200 mesh (customizable; real-world use may vary) |
| Residual solvents | Meets USP |
| Heavy metals | Pb/As/Cd/Hg ≤10 ppm total (ICP-MS typical: ≤3 ppm total) |
| Microbial limits | TAMC ≤1,000 CFU/g; TYMC ≤100 CFU/g; Pathogens: absent (USP <61> <62>) |
| Shelf life | 36 months sealed, 2–8°C, protect from light/moisture |
| Origin | Building 23B1, No.2 Yuanboyuan St., Zhengding Area of China (Hebei) Pilot Free Trade Zone |
Process flow and quality control (in plain language)
Materials: pharma-grade precursors (e.g., 5‑methoxy indole derivatives) → controlled acetylation → purification and recrystallization. Methods: HPLC normalization for assay, GC for solvents, ICP‑MS for heavy metals, and compendial micro tests. Each batch goes through stability pulls (accelerated and real-time) to validate the 36‑month service life claim. Frankly, the documentation is tidy—which saves headaches during audits.
Applications and real-world use
- Dietary supplements: tablets, capsules, sublinguals, gummies, sachet sticks.
- Functional beverages and shots (microencapsulated options reduce bitterness).
- Pharmaceutical intermediate for R&D and pilot formulations.
- Pet wellness (where permitted), and private-label sleep blends.
Case in point: a EU gummy brand cut weight variability by ≈12% after switching to a tighter mesh spec; another client reported cleaner flavor in a 5 mg shot using microencapsulated Melatonin 99% Powder Pharmaceutical Intermediate China Manufacturer Sleeping-Aid.
Vendor comparison (indicative)
| Criteria | Finutra (Manufacturer) | Trader A | Trader B |
|---|---|---|---|
| Assay consistency | ≈99.0–99.5% (recent COAs) | ≈98.5–99.2% | ≈98–99% |
| Lead time | 5–10 days ex‑works (typical) | 10–20 days | 7–15 days |
| Certifications | ISO 9001, food safety system (e.g., FSSC/ISO), GMP-style plant | ISO 9001 (claimed) | Basic QC docs |
| Customization | Mesh, granulation, microencapsulation, premix | Limited mesh | Standard only |
Customization and packaging
Options include 80–200 mesh, DC granules, microencapsulation for taste/oxidation control, and premix blends with magnesium or botanicals. Standard packs: 1 kg foil bags in 25 kg drums; nitrogen-flushed on request.
Testing, data, and standards
- Assay: HPLC (area normalization). Typical lot: 99.3%.
- Solvents: USP <467> class limits—ND in recent GC scans.
- Heavy metals: ICP‑MS; typical total ≤3 ppm.
- Micro: USP <61> <62>—pathogens absent.
- Compliance alignment: USP/Ph. Eur./ChP references where applicable; ISO 9001, food safety system certification.
Customer feedback? “Capsule fill was smoother than expected; no caking in six months at 25°C/60%RH,” one OEM partner told me. Not scientific, but meaningful.
