In the realm of advanced biochemical research, the identification and characterization of synthetic molecules are paramount. For those tracking the development of experimental compounds, the retatrutide peptide number serves as a v Retarutide (LY3437943) is a triple agonist peptide of glucagon receptor (GCGR), glucose-dependent insulin-promoting peptide receptor (GIPR) and glucagon-like ital identifier for researchers seeking to maintain rigorous standards in their laboratory investigations. As someone deeply interested in the structural biology of synthetic peptides, I have spent significant time analyzing the specifications of this compound to understand its role in modern research.
The Chemical Identity: Retatrutide (LY3437943)
When sourcing materials for research, precision is everything. The primary identifier, often referred to as the retatrutide peptide number, is effectively its CAS registry number: 2381089-83-2. Beyond this, the compound is widely recognized in scientific literature under the developmental code LY3437943.
From a structural perspective, this molecule is a sophisticated 39-amino-acid synthetic peptide. It is engineered with a GIP (glucose-dependent insulinotropic polypeptide) backbone and incorporates non-coded residues such as Aib2, Aib20, and aMeL13. These modifications are critical for its stability and potency. Furthermore, the molecule features a C20 fatty acid chain, which is a hallmark of its design as a long-acting triple agonist.

The interest surrounding Retatrutide (LY3437943) stems from its unique pharmacology. It functions as a triple agonist, simultaneously targeting three distinct receptors:
* GCGR [HSA:2642]: The glucagon receptor.
* GIPR: The glucose-dependent insulinotropic polypeptide receptor.
* GLP-1R: The Glucagon-like peptide-1 (GLP-1) receptor.
This "triple-G" profile is what distinguishes it from previous generations of single or dual-agonist peptides. In laboratory settings, this synergy is studied for its profound impact on metabolic signaling pathways. It is essential to note that while recent data, such as the report that Retatrutide hit 28.3% weight loss in the May 2026 trial, generates significant excitement, these results are strictly confined to regulated clinical rese What Is Retatrutide? How It Works, Availability, & More arch environments.
Regulatory and Technical Data
For those managing an inventory of research chemicals, tracking the specific identifiers is standard practice. The substance is also cataloged with specific database codes:
* UNII Record NOP2Y096GV: The primary identifier for the peptide.
* UNII Record LQ42M82ZU6: Associated with the sodium salt form (Retatrutide sodium).
With a molecular weight of approximately 4731 g/mol and the chemical formula C221H342N46O68, it represents a significant achievement in peptide synthesis. When researching this tide, it is important to distinguish between the various salts, such as the acetate form, which may be specified in different laboratory protocols.
Observations on Quality and Research Standards
In my experience evaluating various sources, Retatrutide Injection: Package Insert / Prescribing Info - Drugs.com the purity of the peptide is the most critical factor for accurate data collection. High-quality samples typically boast a purity of 99.4% or higher. When conducting studies, researchers should always verify the CAS number (2381089-83- Substance Class. Protein ; Record UNII. LQ42M82ZU6 ; Record Protection Status. Public record ; Record Status. Validated (BDNUM) ; Record Version. 15. 2) and ensure that the analytical documentation—such as High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) reports—is provided by the supplier.
