About us
Core Chem Labs supplies analytical-grade biochemical reference standards and laboratory research materials to qualified research customers. We exist because researchers deserve a supply chain they can trust — from lot documentation to delivery.
Core Chem Labs supplies analytical-grade biochemical reference standards and laboratory research materials exclusively for qualified in-vitro laboratory research and analytical use by qualified research customers.
CoreChem Labs sources reference materials directly from our partner synthesis facility in Maslenica, Croatia, where initial production and purity assessment take place. Every batch is then reviewed by our U.S.-based team before entering our catalog.
We maintain direct oversight of the full supply chain — from synthesis to shipment — allowing us to guarantee ≥99% purity on every reference material we supply. Each lot is documented and available with a Certificate of Analysis before it reaches a qualified research customer.
Our laboratory
Core Chem Labs maintains on-site chromatography and mass spectrometry capabilities to support peptide purity verification, identity confirmation, and batch-to-batch consistency for reference materials supplied to qualified research customers.
Used for high-performance liquid chromatography analysis of peptide samples. The binary pump system delivers precise solvent gradients at high pressure, separating each peptide from impurities and byproducts before detection — confirming purity and consistency batch to batch.
Left: Thermo Scientific Dionex UltiMate 3000 UHPLC — Separates each peptide sample from impurities and byproducts using ultra-high pressure liquid chromatography.
Right: Thermo Scientific TSQ Quantiva Mass Spectrometer — Identifies each separated component by precisely measuring its molecular weight and fragmenting it to confirm the exact amino acid sequence.
Together: This LC-MS/MS system verifies both purity and identity in a single run, detecting trace contaminants down to parts-per-billion levels.
What sets us apart
Reliable reference materials that support analytical method development, identity verification, and in-vitro laboratory evaluation.
Lot-level documentation and Certificate of Analysis access are central to our quality approach — supporting research traceability.
Clear product specifications, batch identity records, and accessible documentation workflows without consumer or medical positioning.
Every material is intended exclusively for qualified in-vitro laboratory research. No human or animal consumption. No consumer positioning.
Research use only
All products sold by Core Chem Labs are intended strictly for in-vitro laboratory research by qualified professionals. They are not for human consumption, animal consumption, diagnostic procedures, or any other in-vivo application.
