If a supplied lot fails agreed specifications, we’ll replace it at no cost or refund its purchase price in full.
Quality test failed? Free replacement or full refund.
Off-spec? Free replacement or full refund.

About
Headquartered in Shanghai, China, Lyochem synthesises, characterises, documents, and ships sequence-verified research peptides under one quality system. Our buyers are academic laboratories, biotech R&D groups, contract research organisations (CROs), pharmaceutical R&D departments, and shared instrumentation cores across multiple regions.
Stability
Reference-standard qualification includes storage and stability review. We lyophilise to a defined cake, control residual moisture to the Karl Fischer specification, and support re-test dating with a 12-month −20 °C stability series. Review the lot records and storage conditions before using a new batch in your protocol.
Water content is reported when Karl Fischer testing is part of the applicable batch specification.
Re-test dating backed by a documented study, not an assumed shelf life.
Compare the sequence, HPLC, and MS records when qualifying a new lot for your protocol.
Review the recommended solvent and handling conditions for the material.
How we're organized
Lyochem is structured so every buyer-facing decision, pricing, lead time, COA, regulatory review, passes through people who own the relevant function. Inquiries land with sales, but quality and regulatory review every quote before it goes out.
Function
Oversees synthesis, purification, lyophilization, vial filling, and packaging across all production lines. Final sign-off on production schedules and shop-floor changes.
Tenure
10–15 years in synthetic peptide manufacturing
Background
Solid-phase peptide synthesis at a major Chinese CDMO; pharma-API process development for both research-grade and pharmacy-grade material.
Function
Owns analytical methods, stability program, batch release, and COA approval workflow. No batch ships without QA sign-off on the analytical packet.
Tenure
8–12 years in pharmaceutical QA
Background
Documented analytical method development (HPLC, mass spec, Karl Fischer, LAL endotoxin); USP/EP/CP method references where applicable.
Function
Sequence design, non-standard modifications (PEG conjugation, lipidation, copper coordination, D-amino-acid incorporation, intramolecular disulfide bridging), pilot-scale process development.
Tenure
12+ years in synthetic peptide R&D
Background
Doctoral-level training in peptide chemistry; prior experience with custom-sequence synthesis for both research and clinical-development programs.
Function
Direct contact for research-buyer accounts worldwide. Reviews each inquiry for research-institution fit and destination-market eligibility before pricing; written advisory on RUO scope, end-user verification, and cross-border research-reagent import frameworks.
Tenure
8–10 years in research-reagent B2B sales + regulatory
Background
Cross-border research-peptide commercial relationships with academic, biotech R&D, CRO, and pharma R&D buyers; tracking of cross-jurisdictional research-reagent import frameworks across the US, EU, UK, and APAC.
Individual leader identities are disclosed under NDA at the commercial-relationship stage rather than on the public site. Avatars above are monogram-style identifiers, not photographs, they represent the function, not a specific person.
How we work
The manufacturing behind Lyochem has run since 2013 — a peptide-synthesis operation that began supplying research-grade material to academic labs and CROs and grew into an operation covering synthesis, chromatography purification, lyophilisation, vial filling, and characterisation under a single quality system.
Today the same facility releases sequence-verified reference standards for academic laboratories, biotech R&D groups, CROs, pharmaceutical R&D departments, and shared instrumentation cores across multiple regions — strictly Research Use Only.
We focus on batch documentation and the analytical requirements of each research project. We invest in documentation (batch-specific COA, HPLC + Mass Spec, sequence verification by LC-MS/MS, 12-month −20 °C stability series) and in research-institution qualification — every quote is reviewed for research-buyer fit before pricing.
Our analytical methods are aligned with USP <621> (HPLC), USP <1225> (analytical validation), ICH Q2, and EP equivalents. The batch report identifies the methods used and the results recorded for that lot.
First reply under 24 hours from a synthesis chemist or analytical contact. Ask sales for the matching batch COA and confirm which chromatograms, spectra, sequence work, water, or stability data are available or need separate scoping.
