What Is HGH Fragment 176-191?
HGH Fragment 176-191 is supplied as a laboratory research material for controlled experimental work. The product is intended for analytical, biochemical, molecular, or cellular research according to the experimental design selected by the laboratory.
PQRS supplies HGH Fragment 176-191 strictly as a research material. It is not intended for human or veterinary use.
HGH Fragment 176-191 Molecular Profile
Chemical Profile
- Molecular Formula: C78H123N23O22S2
- Molecular Weight: 1799.0 g/mol
- Sequence / Identity: Phe-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe; Cys7-Cys14 disulfide
- PubChem CID: 172966177
Identity Note: Use the free peptide parent CID 172966177 because the PQRS product title does not specify acetate. PubChem CID 172966176 is the acetate-containing record.
2D Molecular Structure

Interactive 3D Structure
Structural Representation: The 2D image is a database-derived molecular structure reference based on the free peptide parent PubChem CID 172966177. The interactive 3D viewer is a computational molecular visualization derived from the referenced chemical structure and is not an experimentally determined structure. These representations are provided for molecular identification and structural reference only and do not constitute product-specific analytical confirmation.
Research Context
Researchers should interpret this material according to its verified molecular or biologic identity, product-specific analytical documentation, and the experimental system being used. Where a single discrete molecular identity is not scientifically appropriate, component-, construct-, or protein-level characterization should be used instead.
Laboratory Research Applications
- Identity and characterization: Evaluation of molecular, peptide, protein, or construct identity using appropriate analytical methods.
- Controlled pathway research: Investigation of relevant biochemical or cellular systems under defined experimental conditions.
- Comparative research: Evaluation alongside appropriate controls or related research materials.
Handling and Preparation
Handle using appropriate laboratory personal protective equipment and validated laboratory procedures. Store and prepare according to the product label, analytical documentation, and laboratory-specific protocol.
For Research Use Only. Not intended for human or veterinary use.
