A Critical Analytical Component for Generic and Innovator Peptide Programs
Reverse-phase HPLC–based peptide characterization is a cornerstone analytical tool in pharmaceutical development, particularly for CMC documentation supporting NDA, ANDA, IND, and CTA submissions. At ResolveMass Laboratories Inc., we operate as a contract research organization (CRO) specializing in regulatory-grade peptide analytical characterization, rather than routine or commercial peptide testing.
Our work is focused on generating scientifically defensible, regulator-ready datasets that support peptide identity confirmation, impurity profiling, batch comparability, and control strategy justification for submissions to Health Canada and the US FDA.
Explore our peptide characterization capabilities to understand how we support generic and innovator peptide programs at every regulatory stage.

Important Notice:
ResolveMass Laboratories works exclusively with pharmaceutical and biotech companies, providing analytical services to support their NDA and ANDA project submissions to FDA and Health Canada for peptides.
We do not offer any testing services to individuals or for personal use. Our services are strictly for business and research purposes only.
Our laboratory operates strictly under a research and development (R&D) framework for the pharma and biotech companies. Testing is intended solely for research purposes to the pharma and biotech companies and is not authorized for clinical or diagnostic decision-making in any forms. For medical use guidance, please consult a licensed healthcare professional.
What Is Peptide Characterization by RP-HPLC?
Understanding Peptide Purity by HPLC Analysis
Understanding HPLC-Based Peptide Characterization
RP-HPLC-based peptide characterization is an analytical strategy used to evaluate the compositional integrity of a peptide material, including:
Batch-to-batch consistency
Main component profiling
Related substance distribution
Truncated or deletion sequences
Oxidative, deamidated, and side-chain modified species
This allows researchers to measure how much of the sample is made up of the desired peptide, versus shortened sequences, deletions, oxidized forms, or side-products.
The Importance of Peptide Purity by HPLC in Life Sciences
- Biological Performance: Even small impurities can alter peptide bioactivity, affecting therapeutic function or lab test results.
- Toxicological Safety: Regulatory bodies require detailed impurity profiles to reduce immunogenic risks.
- Batch-to-Batch Consistency: Quality control is important for manufacturing, formulation, and clinical studies.
- Intellectual Property and Patent Filing: Purity data strengthens patent submissions and new peptide ideas.
For comprehensive evaluations beyond HPLC, we recommend exploring our peptide characterization techniques.
Why HPLC-Based Peptide Characterization Is Critical in Regulatory Science
1. Structure–Activity Integrity
Minor sequence-related or chemical variants can alter biological performance, receptor binding, or degradation behavior—making impurity profiling critical for regulatory acceptance.
2. Impurity Risk and Immunogenicity
Regulators require comprehensive understanding of process- and degradation-related impurities to mitigate safety risks, particularly for injectable peptide APIs.
3. Manufacturing Comparability
HPLC chromatographic fingerprints are used to establish lot-to-lot consistency and support post-change comparability protocols.
4. CMC and IP Strategy
Well-characterized impurity and chromatographic data strengthen:
- ANDA equivalence arguments
- Patent defensibility
- Control strategy sections of Module 3
For multidimensional assessment, RP-HPLC is routinely integrated with LC-MS, HRMS, and orthogonal techniques as part of a full peptide characterization package.

Top 10 Frequently Asked Questions (FAQs)
Do regulators expect impurity identification?
Yes, especially for recurring or above-threshold species in generic submissions.
What chromatographic resolution is expected for peptide APIs?
Resolution must be sufficient to control process- and degradation-related species, not merely achieve high % main component.
