Product Information
This product is for Research Use Only (RUO)
It is not for human consumption. Use only in a laboratory setting by qualified personnel. The FDA has not evaluated this product for safety or efficacy. Any other use is strictly prohibited.
Melatonin Specifications
A neurohormone primarily released by the pineal gland that regulates sleep-wake cycles. Widely used as a dietary supplement for sleep, and supplied here strictly for research applications.
Chemical Properties and Registry Information
| Property | Value |
| Name and synonyms | N-acetyl-5-methoxytryptamine, N-(2-(5-methoxy-1H-indol-3-yl)ethyl)acetamide |
| Material category | Neurohormone |
| Sequence | N-[2-(5-methoxy-1H-indol-3-yl)ethyl]acetamide |
| Molecular formula | C13H16N2O2 |
| Average molecular mass | 232.278 g/mol |
| CAS Registry Number | 73-31-4 |
| PubChem CID | CID 896 |
| Structural features | Indoleamine derived from tryptophan. It is an N-acetylated and O-methylated derivative of serotonin. |
| Appearance | White to off-white crystalline powder |
| Solubility | Slightly soluble in water. Soluble in ethanol, DMSO, and other organic solvents. |
| Physical form | Catalogue vial; exact salt/counter-ion and excipients are batch-specific and must be verified in the CoA and SDS. |
Note: Registry values apply only to the specific molecular entity, sequence, termini, and material form. Batch records take precedence over family-level literature identifiers.
Research Background and Published Evidence
Published research
Melatonin is used in MT1/MT2 receptor-binding and signaling studies, circadian cell-system research and analytical-method development [2,3].
Current scientific understanding
Receptor and structural publications describe defined research systems and do not establish safety, efficacy, or suitability for this catalogue batch. Regulatory classification and permitted supply vary by jurisdiction.
Technical Comparison
| Aspect | This catalogue material | Comparator |
| Identity | Catalogue melatonin material, subject to exact-form batch confirmation | Exact neutral melatonin reference standard |
| Structural distinction | Salt, solvate, formulation and nominal content remain batch-specific | Defined N-acetyl-5-methoxytryptamine without formulation excipients |
| Analytical implication | Confirm identity, form and analyte content against a matching standard and CoA | Reference formula, mass, CAS and CID apply only to the matching neutral molecule |
Quality and Testing
Quality information is batch- and presentation-specific. Use only the report linked to the exact size and lot. A report listed for another size, lot, or similarly named material must not be treated as evidence for this product.
Chromatographic area purity, identity, net peptide or analyte content, water or counter-ion content, sterility, endotoxin, and elemental impurities are different measurements. One result does not establish the others. Only tests supported by a visible, matching report should be regarded as available.
Laboratory Handling and Storage
Store and handle only under the conditions stated on the product label, batch CoA, and SDS. Keep the container secured, correctly identified, and protected from contamination. Do not infer storage, solvent compatibility, or stability from a related compound.
Laboratory preparation, analytical-method selection, risk assessment, personal protective equipment, and waste disposal should follow the applicable SDS and the institution’s approved procedures.
Regulatory and Legal Status
Research-use notice: This material is supplied exclusively by Alma Research Labs for laboratory research by qualified professionals and is not intended for human or veterinary use. Purchasers are responsible for compliance with applicable local requirements.
