Description
Citric acid monohydrate is a pharmacopoeia-quality acid with a minimum assay of 99,5 % according to Ph.Eur. specifications. It carries CAS number 5949-29-1 and the empirical formula C₆H₈O₇·H₂O, with a molar mass of 210,14 g/mol and a density of 1,54 g/cm³. The boiling point is reported as greater than 170 °C, supporting stable use under typical laboratory conditions. Eur. quality, including formulation, analytical preparation and general chemical work in regulated environments. Physical and identity data are provided by manufacturer Carl ROTH. As a crystalline monohydrate, the product is well suited to buffer systems, pH adjustment and procedures where a defined citric acid source is needed. Laboratories working under pharmacopoeial frameworks can rely on the stated purity and documented properties for consistent preparation of solutions and reagents.
