Before you source Magnesium sulfate, understand what it does in Fine Chemicals
Magnesium sulfate (CAS 7487-88-9) looks like an ordinary Fine Chemicals; Fertilizers raw material, yet its behaviour swings a lot across process windows. Across a batch of real selection cases we kept seeing the same few failure points — this page lays them out.
How it works
In Fine Chemicals; Fertilizers, the first split for Magnesium sulfate (CAS 7487-88-9) is 'industrial grade' vs 'food / feed grade' — they are not interchangeable. Food and feed grades carry stricter statutory limits on heavy metals, arsenic, microbes and residues, usually backed by corresponding licences and test reports. Regulatory grade and traceability come before the assay figure. Comparable grades:
- magnesium sulphate anhydrous (CAS 139939-75-6)：a comparable grade often evaluated alongside。
- English：a comparable grade often evaluated alongside。
- 甘氨酸镁：a comparable grade often evaluated alongside。
Key selection dimensions
Confirm the required grade (food / feed / industrial) — never substitute industrial for food or feed use.
Request and verify test reports for heavy metals, arsenic, microbes and residual solvents against the applicable standard or customer spec.
Mind moisture-proof, contamination-free packaging and transport to avoid drift on arrival.
Retain samples of critical lots and keep incoming-inspection records for traceability and retest.
Its typical specs: name Magnesium sulfate, CAS 7487-88-9, formula MgSO4, MW 120.37, standard purity per batch COA, packaging confirmed per order, storage keep sealed in a cool, dry place. Final values follow the batch COA and order confirmation.
The easiest things to miss
Using industrial grade in place of food / feed grade: statutory limits differ and mixing them triggers compliance and safety risk.
Watching assay but ignoring traceability: without the correct grade's test report, even high purity cannot enter the food / feed chain.
Loose storage and transport: moisture or cross-contamination can make a compliant lot fail on arrival.
A few things people ask
Where is Magnesium sulfate used in Fine Chemicals; Fertilizers?
As a common raw material it serves nutritional fortification, stabilisation or process aid; the exact use depends on the finished product and regulatory grade.
Which grade and documents should I confirm when sourcing Magnesium sulfate?
State food / feed grade requirements and verify safety indicators (heavy metals, microbes) test reports against the applicable standard or customer spec.
Can industrial grade be used as food / feed grade?
No. Products here are supplied for industrial and research use; food or feed use requires the correct grade with full compliance documentation.
