Pharmaceutical Reference Standards
For decades LGC has supported the pharmaceutical community with more than 10,000 high-quality reference standards for quality control. Our high quality enables your work to be as accurate as possible, helping you to create better, safer medicines.
Products in our range of more than 5,000 Mikromol API, impurity and excipient reference standards are all manufactured in an ISO/IEC 17025 and 17034 accredited facility - and come with a comprehensive Certificate of Analysis (CoA), ensuring their suitability for both qualitative and quantitative analysis.
Our CoAs provide a complete description of the material they relate to, alongside a summary of the analyses undertaken during the characterisation process - covering assay, purity, stability, uncertainty, homogeneity and more.
