Stable Isotopes Glucuronide Metabolites Vitamin Standards

Pharmaceutical Standards

At Sussex Research Laboratories, we provide high-quality pharmaceutical reference standards essential for accurate quantitation, qualification, and bioanalytical assessments. Our standards support research in active pharmaceutical ingredients (APIs), metabolites, new chemical entities (NCEs), and internal standards across diverse bioanalytical methods. With a focus on precision, reliability, and global trust, our portfolio of pharmaceutical standards includes stable isotope-labelled compounds, glucuronides, and vitamin standards, empowering researchers to drive advancements in drug metabolism, pharmacokinetics, and nutritional science.

Stable Isotopes

Our stable isotope-labelled standards, including deuterated, 13C, and 15N-labelled compounds, are fundamental tools in bioanalytical methods. These isotopes offer unparalleled precision for the quantification and tracking of APIs, metabolites, and impurities. Widely used as internal standards in pharmacokinetic studies, they enhance the accuracy and sensitivity of analytical protocols, making them indispensable in drug development, metabolic research, and environmental studies. Trusted by researchers and bioanalytical laboratories worldwide, our stable isotope standards are recognized for their purity and consistency.

Glucuronide Metabolites

Glucuronides play a critical role in phase 2 drug metabolism, where small molecules undergo glucuronidation, transforming them into more water-soluble substances for excretion. This metabolic pathway, mediated by UDP-Glucuronosyltransferases (UGTs), is essential for detoxifying drugs and xenobiotics. Our glucuronide metabolites, synthesized to the highest standards, allow researchers to study these metabolic processes in detail, supporting drug development, toxicology assessments, and therapeutic monitoring. Used extensively across pharmacology and clinical research, our glucuronide standards are known for their accuracy and relevance to in vivo metabolic pathways.

Vitamin Standards

Our stable isotope-labelled vitamin standards, including Vitamin D2, D3, E, and cholesterol products, as well as their hydroxy metabolites, are trusted by researchers and global nutrition companies. These standards enable the precise measurement of vitamin levels in nutritional and metabolic studies, ensuring accuracy in clinical diagnostics and therapeutic interventions. With superior quality and reliability, our vitamin standards are used in analytical protocols across multiple continents, serving as gold standards in bioanalytical research. Whether for clinical nutrition studies or metabolic tracking, these standards provide the essential accuracy required for cutting-edge research.
