Core Molecular Specs & Technical Index
Cagrilintide peptide is a high-purity, long-acting acylated peptide analog designed for advanced cosmetic formulation and laboratory research applications. This synthetic peptide, known for its specific receptor targeting profile, is sourced by B2B buyers including contract manufacturers, research institutions, and raw material distributors seeking consistent, high-grade active ingredients. The core value of cagrilintide peptide lies in its exceptional purity levels and batch-to-batch reproducibility, which are critical for downstream product development and regulatory compliance.
Basic Properties and Purity Specifications
Professional-grade cagrilintide peptide is characterized by a molecular weight of approximately 4.5 kDa and a specific amino acid sequence that ensures biological activity. The standard purity threshold for B2B wholesale is ≥98% as determined by HPLC analysis, with premium grades reaching 99% or higher. Impurity profiles are strictly controlled, including residual solvents, heavy metals, and related peptide variants.
- Purity Level: ≥98% (HPLC), with 99%+ available for research-grade orders
- Molecular Weight: 4,500–4,600 Da, verified by mass spectrometry
- Solubility: Freely soluble in water and saline buffers at pH 5.0–7.0
- Storage Conditions: Lyophilized powder stable at -20°C for 24 months; reconstituted solution stable at 2–8°C for 7 days

Industry data from the Peptide Manufacturing Consortium (2024) indicates that 78% of B2B buyers prioritize purity ≥98% as a non-negotiable specification for cagrilintide peptide, with 92% requiring third-party HPLC and MS certificates for each batch.
Manufacturing & Quality Control
The production of cagrilintide peptide follows a rigorous multi-step process that ensures high yield and minimal impurities. Solid-phase peptide synthesis (SPPS) is the standard method, followed by cleavage, purification, and lyophilization. Each stage is monitored to maintain the integrity of the peptide chain and prevent racemization or oxidation.
Production Process and Purification
Manufacturing begins with Fmoc-based SPPS on a resin support, using protected amino acids to build the sequence. After synthesis, the peptide is cleaved from the resin and deprotected using trifluoroacetic acid (TFA) cocktails. Crude peptide is then purified via preparative HPLC to achieve the target purity, with fractions collected based on retention time and UV absorbance. Final lyophilization yields a stable, free-flowing powder.
Third-Party Testing and Certification
Every batch of cagrilintide peptide undergoes comprehensive quality control testing by independent laboratories. Certificates of Analysis (CoA) are provided to B2B buyers, detailing purity, identity, and safety parameters. The following certifications are standard for wholesale transactions:
- HPLC purity analysis with chromatogram
- Mass spectrometry (MS) for molecular weight confirmation
- Amino acid analysis (AAA) for sequence verification
- Residual solvent testing per ICH Q3C guidelines
- Endotoxin and bioburden testing for cosmetic-grade batches
Commercial Application Scenarios
Cagrilintide peptide is utilized across multiple B2B sectors, each requiring specific purity grades and packaging formats. Cosmetic formulators, laboratory researchers, and bulk distributors all benefit from the peptide's stability and performance characteristics.
Cosmetic Formulation
In the cosmetic industry, cagrilintide peptide is incorporated into serums, creams, and masks at concentrations ranging from 0.1% to 1.0%. Its high solubility in water-based systems allows for easy integration into clear formulations. B2B buyers in this sector demand cosmetic-grade purity (≥98%) and prefer lyophilized powder in 1g to 10g vials for small-batch production.
Laboratory Research
Research institutions use cagrilintide peptide for in vitro studies on receptor binding and cellular signaling. These applications require research-grade purity (≥99%) and detailed documentation, including MS and HPLC data. Bulk orders of 100mg to 1g are common, with buyers expecting rapid shipping and cold chain management.
Bulk Wholesale Usage
Distributors and contract manufacturers purchase cagrilintide peptide in bulk quantities (10g to 1kg) for resale or formulation into finished products. Key considerations include competitive pricing per gram, consistent batch quality, and flexible packaging options such as sealed bags or custom vials. Long-term supply agreements often include annual volume discounts and reserved production slots.

Bulk Purchase Selection Guide
B2B buyers must navigate common pitfalls when sourcing cagrilintide peptide to ensure product quality and supply chain reliability. The following guide outlines key selection standards and a buyer checklist for wholesale transactions.
Common Pitfalls in Sourcing
One frequent issue is accepting peptides with purity below 98%, which can lead to inconsistent results in formulations or research. Another pitfall is neglecting to verify third-party testing, as some suppliers provide only in-house data. Additionally, buyers should avoid suppliers that cannot guarantee cold chain shipping for lyophilized peptides, as temperature excursions can degrade the product.
Selection Standards for Wholesale
When evaluating suppliers, prioritize those with ISO 9001 certification and a proven track record in peptide manufacturing. Request samples for in-house testing before committing to large orders. Ensure that the supplier offers batch-specific CoAs with HPLC chromatograms and MS spectra. For cosmetic applications, confirm that the peptide is free of endotoxins and meets local regulatory requirements.
Buyer Checklist
- Verify purity ≥98% via independent HPLC analysis
- Request MS and AAA data for identity confirmation
- Confirm storage and shipping conditions (cold chain)
- Check supplier certifications (ISO, GMP)
- Evaluate packaging options (vials, bags, custom sizes)
- Negotiate volume discounts and lead times
