Sodium benzoate (CAS 532-32-1): Sourcing & QC Notes from a Pharmaceutical Intermediates & APIs Perspective
Before sourcing Sodium benzoate (CAS 532-32-1), it helps to understand the role it plays in Pharmaceutical Intermediates & APIs; Hot Products; Preservatives — often more useful than comparing a spec sheet line by line. This page takes a sourcing and QC view: how to select it and which indicators actually move the result; comparable grades are in site search for 苯甲酸钠.

2. Role & mechanism in Food & Feed Raw Materials
In Pharmaceutical Intermediates & APIs; Hot Products; Preservatives, the first split for Sodium benzoate (CAS 532-32-1) 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:
- PARA-ARSENOSOBENZOICACID,SODIUMSALT (CAS 1197-16-6)：a comparable grade often evaluated alongside。
- o-Iodobenzoic acid sodium salt (CAS 2532-17-4)：a comparable grade often evaluated alongside。
- SODIUM P-CHLOROBENZOATE (CAS 3686-66-6)：a comparable grade often evaluated alongside。
Selection notes
- 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指标 drift on arrival.
- Retain samples of critical lots and keep incoming-inspection records for traceability and retest.
Common pitfalls
- 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.
3. FAQ
Where is Sodium benzoate used in Pharmaceutical Intermediates & APIs; Hot Products; Preservatives?
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 benzoate?
