Taurine (2-aminoethanesulfonic acid) is supplied as a pharmaceutical secondary standard certified reference material (CRM) for analytical and quality control applications. This material is traceable to USP primary standards and produced under ISO 17034 and ISO/IEC 17025 requirements, ensuring suitability for validated analytical methods and regulatory environments.

Provided in neat form, taurine is a small-molecule sulfonated amino acid commonly used as a reference standard in pharmaceutical testing, food and beverage analysis, and biochemical research. It is suitable for chromatographic techniques including HPLC and GC and may be used for method development, system suitability testing, and quantitative analysis.

Taurine plays important roles in biological systems, including osmoregulation, bile salt formation, and neuromodulation. As a CRM, it supports accurate identification and quantification of taurine in pharmaceutical dosage forms, nutritional products, and complex matrices.
