Sodium Citrates (CAS 994-36-5): Sourcing & QC Notes for Chelating agent
When a sourcing manager asks us whether our Sodium Citrates (CAS 994-36-5) spec is acceptable, we don't just say yes or no. We look at your Chelating agent conditions first, then back into the indicators to verify. This page follows that same method.

Figures above are published / typical information; final values follow the batch COA and order confirmation.
Key physical data: molecular formula C6H5Na3O7, molecular weight 258.07 g/mol, CAS 994-36-5, melting point 300 °C. These are published physical properties; purity and packaging follow the batch COA and order confirmation.
The role it plays in Chelating agent
This is the part that's most counter-intuitive:In Chelating agent, the first split for Sodium Citrates (CAS 994-36-5) 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:
- Calcium Carbonate (CAS 471-34-1)：a comparable grade often evaluated alongside。
- Calcium Chloride (CAS 10043-52-4)：a comparable grade often evaluated alongside。
- Potassium chloride (CAS 7447-40-7)：a comparable grade often evaluated alongside。
- Vitamin E (CAS 59-02-9)：a comparable grade often evaluated alongside。
- calcium ascorbate dihydrate (CAS 5743-28-2)：a comparable grade often evaluated alongside。
- 2,3-didehydro-3-O-sodio-D-erythro-hexono-1,4-lactone (CAS 6381-77-7)：a comparable grade often evaluated alongside。
- Phospholipids：a comparable grade often evaluated alongside。
- Calcium lactate (CAS 814-80-2)：a comparable grade often evaluated alongside。
Checks worth running before you order
- If I had to pick one, it'd be: 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.
Mistakes people make
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.
Questions we often get
Where is Sodium Citrates used in Chelating agent?
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 Sodium Citrates?
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.
