Buying sarcosine (CAS 107-97-1) means matching the grade to the end use – surfactant manufacture, nutrition or pharmaceutical synthesis. This guide explains each specification item and what to confirm.
1. The Specification Sheet
| Parameter | Value | Why it matters |
|---|---|---|
| Appearance | White to off-white microcrystalline powder | Visual QC |
| Assay | 98% min | Reaction yield for surfactants |
| Loss on drying | 0.5% max | Moisture control, storage stability |
| Residue on ignition | 0.5% max | Inorganic/ash content |
| Heavy metal (Pb) | 10 ppm max | Safety for cosmetic/nutrition use |
| Melting point | 205-215 °C | Identity and purity indicator |
2. What a COA Should Show
- Assay by titration/HPLC with method.
- Loss on drying, residue on ignition.
- Heavy metals (Pb) measured value.
- Melting point, appearance, batch data.
3. Grade Selection
- Surfactant grade: assay ≥98%, moisture/ash control, colour.
- Cosmetic/nutritional grade: tighter heavy-metal limits and consistent particle size.
- Pharma/intermediate grade: batch documentation and impurity profile per customer spec.
4. Packaging and Storage
- 25 kg fibre drums or bags with PE liner; smaller packs for trials.
- Store sealed, cool and dry – sarcosine powder picks up moisture.
5. FAQ
Can I order a small trial quantity?
Yes – trial packs are available; contact us for details.
How should sarcosine be stored?
Sealed, cool, dry and away from oxidizers; reseal after sampling to avoid moisture uptake.
