Analytical standards and CRMs.

High-purity analytical standards for API quantification: method development and validation, regulatory compliance.

Ultra-trace standards for the known nitrosamines and drug-substance-related ones (NDSRI), following evolving EMA and FDA guidance.

Well-characterised standards for method validation and quality control, with lot certificate of analysis.

Metabolite reference standards for pharmacokinetics, biomarker discovery, metabolic profiling and clinical research.

Internal standards for mass spectrometry quantification: metabolomics, pharmacokinetics, environmental analysis.

Pharmacopoeial standards (EP, USP, BP) for routine quality control.

Certified reference materials for residues in food, feed and environmental samples; single and mixed, neat and in solution.

Aflatoxins, ochratoxin A, DON, zearalenone, fumonisins, ergot alkaloids: standards for sensitive detection and regulatory monitoring.

Standards to identify and quantify per- and polyfluoroalkyl substances in environmental, food and biological samples, down to ultra-trace levels.

Oligomers, plasticisers, esters and food contact material contaminants.

Single and mixed standards in acetonitrile, acetone, methanol or other solvents, at certified concentration.

Monodisperse standards to calibrate and validate particle sizing instruments: microscopy, light scattering, filtration testing.
