Chemical & Physical Characteristics

Andarine S4 is a non-steroidal, orally bioavailable compound classified within the SARM family. Its molecular architecture includes a trifluoromethyl group and a nitro-substituted aniline moiety, conferring notable receptor-binding selectivity that makes it a subject of ongoing academic and pharmaceutical research. In its powder form, S4 presents as a fine crystalline solid with moderate solubility in DMSO and ethanol, and limited aqueous solubility. These physicochemical properties are well-characterised and support its use in a variety of in-vitro assay formats.

Purity & Analytical Verification

Every batch of S4 Andarine powder supplied by EU Chems Lab is confirmed at ≥98% purity through high-performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR) spectroscopy. Mass spectrometry (MS) is employed to verify molecular identity. Analytical certificates of analysis (CoA) are available upon request and accompany each order, providing full transparency regarding purity levels, residual solvent profiles, and structural confirmation data.

Quality Control & Batch Integrity

EU Chems Lab operates a stringent multi-stage quality control protocol applied at the point of manufacture, during transit, and prior to dispatch. Batch integrity is maintained through sealed, inert-atmosphere packaging and climate-controlled storage. Each batch is individually coded and traceable, enabling complete audit trails for research documentation and institutional compliance requirements. Only batches meeting our ≥98% purity threshold are released for sale, ensuring consistent research-grade performance across all orders.

Safety, Handling & Laboratory Precautions

S4 Andarine powder should be handled exclusively by trained laboratory professionals in a properly equipped research environment. Standard laboratory personal protective equipment (PPE) is required, including nitrile gloves, safety goggles, and a laboratory coat. Work should be conducted in a fume hood or under appropriate ventilation. Avoid inhalation of dust and contact with skin or mucous membranes. Refer to the Safety Data Sheet (SDS) for full hazard classification, first-aid measures, and disposal guidance in accordance with local and EU regulatory requirements. This compound is not intended for human or veterinary use under any circumstances.

Packaging, Labeling & Storage

S4 Andarine powder is packaged in pharmaceutical-grade, airtight containers under inert atmosphere to preserve chemical stability throughout transit and storage.
