Who Supplies Chromium Chloride (Chloride Form) to Pharma?
Chromium chloride is supplied globally through specialist inorganic chemical distributors and direct manufacturers. The practical supplier universe for pharmaceutical use depends on the grade: chromium(III) chloride (CrCl₃) versus chromium(II) chloride (CrCl₂), and on whether the buyer needs pharmaceutical grade specifications versus standard industrial grade.
What forms of “chromic chloride” supply chains typically cover?
In pharmaceutical procurement, “chromic chloride” usually maps to one of these:
- Chromium(III) chloride (CrCl₃), the dominant salt in commercial catalogs.
- Chromium(II) chloride (CrCl₂), less common and typically handled with higher reactivity controls.
Supply continuity and compliance documentation differ by form because of stability, moisture sensitivity, and impurity control.
Which supplier categories do pharma buyers use for chromium chloride?
Chromium chloride procurement typically runs through four channels:
- Global inorganic chemical manufacturers producing chromium chloride salts under controlled specs.
- Distributors that sell branded lots with COA support and lead-time consolidation.
- Specialty chemical suppliers focused on high-purity inorganic reagents.
- Regulated chemical sourcing partners that support documentation packs used for drug substance and drug product supply chains.
Which companies supply chromium chloride (CrCl₃) at scale?
Below are known commercial suppliers that list chromium(III) chloride (CAS-aligned catalog items) in their product ranges. Lead times, grades, and documentation packages vary by listing.
| Supplier |
Common catalog coverage |
Notes for pharma procurement |
| Alfa Aesar (Thermo Fisher Scientific) |
CrCl₃ grades (various purities) |
COA and batch traceability are standard for reagent-type supply. |
| Sigma-Aldrich / Merck |
Chromium(III) chloride |
Widely used inorganic catalog supplier; grade depends on listing. |
| TCI Chemicals |
Chromium(III) chloride |
Common for research and process supply, depends on grade. |
| Acros Organics (Thermo Fisher) |
Chromium(III) chloride |
Often aligned with reagent-grade inorganic offerings. |
| Fisher Scientific |
Chromium(III) chloride via distribution |
Typically routes through manufacturer partners; grade and documentation depend on the exact SKU. |
| Shaanxi Ruihe / China inorganic chemical manufacturers (varied brands) |
Chromium(III) chloride |
Many offer industrial and higher-purity grades; pharma suitability depends on audited quality systems and impurity specs. |
Because supplier availability is SKU-specific, procurement teams typically match:
- salt form (CrCl₃ vs CrCl₂),
- purity tier (e.g., “ACS” vs “analytical” vs “high purity”),
- impurity limits (Fe, sulfate, alkali metals, heavy metals),
- water content / hydration state,
- particle form and handling requirements.
Which suppliers typically cover chromium(II) chloride (CrCl₂)?
Chromium(II) chloride has narrower commercial availability. Where supplied, it is usually offered under stricter handling conditions (air/moisture sensitivity) and often in smaller pack sizes.
Typical suppliers that carry CrCl₂ on catalog listings include specialty reagent distributors, but availability varies year to year by inventory and regulatory handling controls.
What documentation packs matter for pharma use of chromium chloride?
Pharma buyers commonly require a documentation package aligned to cGMP and quality risk management, such as:
- Certificate of Analysis (COA) with batch-specific impurity data
- Certificate of Compliance / Compliance letters
- SDS and shipping documentation
- TSE/BSE statements (if relevant to upstream policy)
- GMP manufacturing statement or quality system description
- Traceability to raw material sources for higher-tier grades
Procurement teams also screen impurity profiles that drive patient risk and drug substance specifications, including:
- iron and other transition metals
- chloride impurities outside the target stoichiometry
- heavy metal contaminants
- residual catalysts or process-related impurities (where relevant)
- microbial or endotoxin only when the salt enters aqueous manufacturing steps with direct patient exposure (risk-based)
How do you narrow suppliers to a realistic shortlist?
Shortlist decisions usually hinge on three gating items:
- Salt form correctness: CrCl₃ vs CrCl₂, hydration state, and concentration.
- Quality tier fit: pharmaceutical-grade or high-purity grade with impurity limits aligned to the internal specification.
- Regulatory/document support: COA completeness, traceability, and quality system readiness.
Practically, procurement teams request samples only after aligning catalog specs to the intended use.
Key Takeaways
- “Chromic chloride” supply is dominated by chromium(III) chloride (CrCl₃); chromium(II) chloride (CrCl₂) is narrower and more handling-sensitive.
- Pharma-grade suitability is determined by SKU-specific purity tier, impurity limits, and documentation pack completeness, not just by the supplier name.
- The most common supplier universe includes Alfa Aesar (Thermo Fisher), Sigma-Aldrich (Merck), TCI Chemicals, and other major distributors/manufacturers; China-based inorganic producers also exist but require audit-level confidence for pharma use.
FAQs
1) Is “chromic chloride” the same as chromium(III) chloride?
In most pharmaceutical and chemical catalogs, the term maps to chromium(III) chloride (CrCl₃). Confirm the exact salt and CAS-aligned listing used for the procurement request.
2) Who supplies chromium(III) chloride at scale for laboratory and process use?
Major reagent and specialty inorganic suppliers such as Alfa Aesar (Thermo Fisher), Sigma-Aldrich (Merck), and TCI Chemicals list chromium(III) chloride across multiple purities.
3) Do distributors sell cGMP pharmaceutical-grade chromium chloride?
Some distributors can source higher-tier materials, but the cGMP readiness depends on the manufacturer behind the SKU and the quality documentation they provide.
4) Why is chromium(II) chloride harder to source?
CrCl₂ is more air and moisture sensitive, so suppliers impose stricter handling, storage controls, and packaging requirements, and inventory cycles can be shorter.
5) What impurity data should be checked first in a COA?
Procurement typically focuses on iron and other heavy metal impurities, sulfate/alkali impurities, residual process contaminants (if applicable), and water content where it affects stability or downstream formulation.
