Physical Properties
Pinealon is a synthetic tripeptide composed of three amino acids forming a short regulatory peptide sequence. Its compact molecular structure supports strong aqueous solubility and efficient laboratory handling. Due to its minimal chain length, the peptide demonstrates predictable stability characteristics when stored in lyophilized form. Protection from moisture, light exposure, and repeated freeze–thaw cycles helps maintain structural integrity and analytical consistency during research applications.
Analysis & Documentation
Identity
Each production lot is checked against the reference structure recorded for this compound:
- Classification — Synthetic tripeptide (pineal-derived bioregulator)
- Molecular formula — C₁₄H₂₅N₅O₄
- Expected mass — ~327.38 Da
- CAS registry — Not assigned (synthetic short peptide)
- Chain length — 3 amino acids

Analytical Methods
Testing is carried out per lot by an independent laboratory. The methods measure what the material is and how much of it is the target compound:
- RP-HPLC — reverse-phase separation of the target from process-related impurities; purity is reported as area percent of the main peak
- Mass spectrometry — observed mass compared against the expected molecular mass above
- Retention time — compared against a reference standard run under the same conditions
- Chromatogram — reproduced on the certificate so the peak and any shoulders can be inspected directly

Laboratory Handling and Storage Protocols
Lyophilized Powder Storage
- Store at –20°C to –80°C in the original, sealed vial
- Protect from light exposure and moisture
- A desiccated storage environment is recommended
- Stability data suggests extended stability when stored at −20 °C or below.
Reconstituted Solution Storage
- Short-term storage: Up to 7 days at 4°C
- Long-term storage: Store at –20°C in aliquots
- Use single-use aliquots to preserve peptide integrity
- Minimize freeze–thaw cycles; single-use aliquots are strongly recommended
Stability Characteristics
Pinealon is a synthetic tripeptide research compound that demonstrates stable handling characteristics when managed according to standard peptide laboratory protocols. Proper cold storage of the lyophilized material, careful reconstitution, and minimized freeze–thaw exposure help maintain structural integrity and solubility. When handled appropriately, Pinealon supports consistent use in in vitro and analytical research applications.
Frequently Asked Questions
What is Pinealon?
Pinealon is a short synthetic peptide from the Khavinson bioregulator series, supplied as a lyophilized powder for laboratory use.
Is Pinealon a single peptide or a complex?
Pinealon is generally described as a short-chain peptide complex composed of low–molecular weight amino acid sequences, rather than a single long-chain peptide.
How does Pinealon differ from Epitalon?
Pinealon is classified within the cytomedine family and consists of shorter peptide fragments; Epitalon is a specific tetrapeptide sequence. They are distinct compounds with distinct CAS registrations.
How is Pinealon supplied?
Pinealon is typically supplied as a lyophilized (freeze-dried) powder in sealed research vials to preserve stability during storage and shipment.
How should unreconstituted Pinealon be stored?
Lyophilized Pinealon should be stored:
-
Long-term: −20 °C to −80 °C
-
Short-term: 2–8 °C
Keep vials sealed and protected from light and moisture until use.
How should reconstituted Pinealon be handled and stored?
Once reconstituted:
-
Store at 2–8 °C for short-term laboratory use
-
For extended storage, aliquot and freeze at −20 °C or below
-
Minimize freeze–thaw cycles using single-use aliquots
-
Gently swirl to mix; avoid vigorous agitation
Does Pinealon require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch of Pinealon, verifying identity, purity, and analytical testing results to ensure research quality and traceability.
Is Pinealon FDA-approved?
No. Pinealon is not FDA-approved as a drug, supplement, or therapeutic product. It is sold exclusively as a research compound and must not be marketed or used for diagnostic, therapeutic, or consumption purposes.
