Ectoine is a cyclic amino-acid derivative supplied for laboratory and biochemical research applications. Registered under CAS number 96702-03-3, it corresponds to the empirical formula C₆H₁₀N₂O₂ and has a molar mass of 142,16 g/mol. The product is offered in a 50 g pack size that suits formulation trials, stability studies, and experimental work requiring a defined compatible-solute-type molecule. Laboratories use ectoine when they need a characterised small heterocycle for buffer systems, stress-response models, or comparative biochemical assays under controlled conditions. Identity parameters—CAS designation, molecular formula, and molar mass—support accurate ordering, documentation, and batch tracking. This material is available from manufacturer Carl ROTH as part of a broader chemicals and biochemicals range intended for research environments. The 50 g unit provides a practical quantity for multi-experiment programmes without introducing claims beyond the stated manufacturer specifications. Ectoine therefore fits research workflows that call for a well-identified C₆H₁₀N₂O₂ compound in a convenient laboratory pack.
