PEA Powder Supplier Guide: Purity, Particle Size & COA
PathGene supplies palmitoylethanolamide (PEA) powder, CAS 544-31-0, with a ≥99.0% HPLC purity specification. Batch PGPEA-260304 recorded 99.83%. Evaluation samples, batch COA and bulk supply are available, with a published MOQ of 1 kg. For a quotation, send your quantity, particle-size requirements, packaging and destination.
What is palmitoylethanolamide powder?
Palmitoylethanolamide is also called PEA, palmitoyl ethanolamide or N-palmitoyl ethanolamine. PubChem lists CAS 544-31-0 and molecular formula C18H37NO2. Using the full ingredient name and CAS in an inquiry helps distinguish this material from other products abbreviated PEA.
PathGene's material is a white to off-white crystalline powder. For capsule, tablet or powder-blend development, evaluate the sample against the intended processing conditions and dosage form. The PEA powder product page brings together the supply specification, batch results and sample inquiry.
PEA powder specification and actual batch results
The original in-house COA identifies batch PGPEA-260304, produced March 4, 2026 and tested March 7, 2026. It records 25 kg/barrel packaging and a two-year shelf life.
| Quality item | COA specification | Batch result |
|---|---|---|
| HPLC purity | ≥99.0% | 99.83% |
| Loss on drying | ≤1.0% | 0.02% |
| Residue on ignition | ≤0.5% | 0.049% |
| Methanol | ≤0.3% | Not detected |
| Ethanol | ≤0.5% | Not detected |
| Ethyl acetate | ≤0.5% | Not detected |
These results provide a concrete starting point for supplier qualification. The 99.83% result belongs to this batch; the release specification remains ≥99.0% by HPLC. Request the COA matching the lot offered for your order. The reported residual-solvent results describe the listed tests and should be read with their methods and reporting limits.

How to specify particle size for a PEA project
Particle-size requirements deserve their own line in a purchase specification. The term “micronized PEA” alone does not define an acceptance criterion. A useful inquiry states:
- The target distribution, such as D10, D50 and D90, with units.
- The measurement method and sample-dispersion conditions, or the required sieve method and mesh standard.
- The intended format: capsule, tablet, powder blend or another development project.
- The checks planned for the sample, such as flow, mixing uniformity, dispersion or dissolution under the chosen test conditions.
PathGene accepts particle-size requirements for project discussion. Agree the offered grade, measurement method and sample criteria before placing a bulk order. The published COA above does not itself certify a micronized or ultramicronized grade.
From evaluation sample to bulk PEA supply
A productive sample trial connects quality checks with manufacturing needs. First identify the sample lot and review its COA. Then assess the powder in your process, recording the formulation, equipment, mixing sequence and acceptance criteria. Use those results to finalize the purchase specification.
The product page lists sample availability and packaging options of 1 g, 100 g, 1 kg and 25 kg. The bulk MOQ is 1 kg; sample requests and commercial orders can be discussed separately. Storage is sealed, cool, dry and protected from light. Confirm the packaging and delivery schedule for the quantity being quoted.
For the documentation stage, see our bulk ingredient documentation checklist and sample evaluation checklist.
Request a PEA powder quotation
Send required quantity, destination country, application, particle-size requirements, packaging and documentation needs. PathGene can align the quotation with your raw-material specification and sample plan. Start with the palmitoylethanolamide powder supply page to request a sample, batch COA or bulk quotation.

Frequently Asked Questions
What is the PathGene PEA purity specification?+
The specification is ≥99.0% by HPLC. Batch PGPEA-260304 recorded 99.83%; request the COA for the lot offered.
Does a high HPLC purity define a micronized grade?+
No. Particle size is a separate property. State D10, D50, D90 or the required mesh specification and measurement method.
Can I request a PEA powder sample?+
Yes. Send the sample quantity, target format, particle-size needs and destination to discuss evaluation.
What should I send for a bulk PEA quotation?+
Send quantity, destination country, application, particle-size requirements, packaging and documentation needs. The published bulk MOQ is 1 kg.
