Description
CAPSO sodium salt is a buffer salt offered as PUFFERAN® with a minimum purity of 95 %, CAS number 102601-34-3 and empirical formula C₉H₁₈NO₄NaS. The molar mass is 259,3 g/mol and the boiling point is 601,2 °C, supporting calculation and documentation in buffer preparation. It is supplied in a 25 g plastic pack for laboratory use in performance-materials and buffer-salt applications. PUFFERAN® grade material from manufacturer Carl ROTH is intended where CAPSO chemistry in the sodium-salt form is specified for buffering systems. Stated purity, formula and molar mass allow accurate weighing and composition control when building working buffers. The compact 25 g plastic unit suits method development, stock solutions and routine bench consumption. Clear identity data including CAS 102601-34-3 help align orders and inventory with published protocols that call for CAPSO sodium salt. This presentation supports laboratories that standardise on defined buffer salts with transparent physical and chemical specifications.
