Morpholine (CAS 110-91-8) is a clear, hygroscopic liquid amine with real handling considerations — it is corrosive, flammable and regulated in some regions. Buying it well means checking the right specifications and following the right safety practices. This purchasing guide covers the specification sheet, the COA, packaging, storage and the supplier checklist for morpholine.
1. Reading the Specification
| Parameter | Typical value | Why it matters |
|---|---|---|
| Purity | 99%+ | Active content |
| Appearance | Clear, colorless liquid | Visual QC |
| Water content | Low (<0.5%) | Affects reactions and storage |
| Amine value | Per spec | Active amine content |
| Boiling point | ~129 °C | Handling reference |
2. What a Complete COA Should Contain
- Product name and CAS number (110-91-8)
- Batch number and production date
- Purity and water (measured)
- Amine value and appearance
- Test methods and quality manager signature
3. Packaging, Storage and Handling
- Packaging: typically drums (200 kg), IBC totes or bulk; keep sealed (hygroscopic).
- Storage: cool, dry, ventilated; away from acids and oxidizers. It is flammable.
- Handling: corrosive and irritating — gloves, goggles, ventilation; follow the SDS.
- Shelf life: typically 24 months when stored properly.
4. Regulatory Notes
- Morpholine is watch-listed in some jurisdictions (dual-use/corrosion-inhibitor chemical) — confirm export/import controls for your route.
- Classified as corrosive/flammable in transport — confirm the SDS and shipping classification with your forwarder.
5. How to Verify Quality on Arrival
- Check containers and labels against the COA batch number.
- Visual check: clear liquid, no discoloration or phase separation.
- Verify purity and water against the COA.
- Keep a retained sample per batch.
6. Supplier Checklist
- Manufacturer vs trader — manufacturers control purity consistency.
- Consistent COA with measured purity/water on every batch.
- Correct dangerous-goods documentation for transport.
- Stable supply and reasonable lead time.
- Price comparison on a per-kg basis at the same grade.
