Product Overview

S-4, widely referenced in the scientific literature as Andarine, is a selective androgen receptor modulator (SARM) that has attracted significant interest within the pharmacological and biochemical research communities. EU Chems Lab makes it straightforward to buy S-4 (Andarine) Capsules online with confidence, offering a pre-dosed capsule format that simplifies weighing, handling, and dosing consistency across multi-replicate in vitro study designs. Fast EU dispatch and transparent batch documentation make this one of the most sought-after research chemicals available for sale through our platform.

Chemical Identity & Classification

S-4 (Andarine) belongs to the arylpropionamide class of non-steroidal selective androgen receptor modulators. Its systematic IUPAC designation is (2S)-3-(4-acetamido-phenoxy)-2-hydroxy-2-methyl-N-[4-nitro-3-(trifluoromethyl)phenyl]propanamide, and it is catalogued under CAS number 401900-40-1. As a SARM, it is structurally distinct from classical steroidal androgens, making it a valuable investigational tool for researchers studying androgen receptor binding, selectivity, and downstream signalling pathways in controlled laboratory environments.

Chemical & Physical Characteristics

• CAS Number: 401900-40-1
• Molecular Formula: C₁₉H₁₈F₃N₃O₆
• Molecular Weight: 441.35 g/mol
• Appearance: Off-white to pale yellow crystalline powder, encapsulated in hard-shell gelatin or HPMC capsules
• Solubility: Soluble in DMSO and ethanol; limited aqueous solubility
• Storage Stability: Stable under recommended storage conditions for the duration of the stated shelf life

Purity & Analytical Verification

Every batch of S-4 (Andarine) Capsules supplied by EU Chems Lab is independently verified to confirm a minimum purity of ≥98% by high-performance liquid chromatography (HPLC). Nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) are additionally employed to confirm structural identity and rule out interfering by-products or degradation compounds. Certificates of Analysis (CoA) are available upon request and accompany each order, providing full traceability for institutional procurement and internal quality assurance records.

Quality Control & Batch Integrity

Batch integrity is a non-negotiable priority at EU Chems Lab. Each production run of S-4 capsules is assigned a unique batch reference number, enabling end-to-end traceability from raw API sourcing through encapsulation and final packaging. Content uniformity testing is performed to verify that each capsule delivers a consistent quantity of active material within tightly controlled tolerances, supporting reproducible experimental outcomes across independent replicates. Our quality management protocols are designed to meet the expectations of professional research institutions and regulatory-grade laboratory environments.

Safety, Handling & Laboratory Precautions

S-4 (Andarine) Capsules are supplied exclusively as a laboratory research chemical. Standard laboratory safety precautions must be observed at all times when handling this material. Researchers should wear appropriate personal protective equipment (PPE) including nitrile gloves, safety eyewear, and a laboratory coat. Handle in a well-ventilated area or under a fume hood where required by local institutional safety protocols. Refer to the applicable Safety Data Sheet (SDS) prior to use. This product is not intended for human or veterinary use, and must not be administered to any living organism.

Packaging, Labeling & Storage

S-4 (Andarine) Capsules from EU Chems Lab are packaged in sealed foil blister packs or light-resistant screw-cap bottles, selected to protect product integrity during transit and storage. All packaging is clearly labelled with batch number, purity grade, CAS number, and the mandatory research-use-only designation. Capsules should be stored in a cool, dry environment away from direct light, moisture, and heat sources. Recommended storage temperature is 2–8 °C for long-term stability, or at room temperature for short-term laboratory use.

Intended Research Use & Market Positioning

S-4 (Andarine) Capsules are positioned as a premium-grade investigational tool for academic institutions, contract research organisations (CROs), and pharmaceutical research laboratories engaged in androgen receptor biology, SARM pharmacology, and related in vitro screening programmes. The pre-dosed capsule format offers a practical advantage over raw powder for researchers requiring standardised dosing units across large experimental cohorts. EU Chems Lab is committed to supplying the European research community with reliable, competitively priced, high-purity research chemicals for sale with rapid fulfillment.
