Cobalt(II)-nitrate hexahydrate, min. 98 %, p.a., ACS, 50 g, plastic

Cobalt(II) nitrate hexahydrate is an inorganic cobalt salt supplied at min. 98 % purity in p.a., ACS quality for analytical and preparative laboratory work. The compound has the empirical formula Co(NO₃)₂ · 6 H₂O, a molar mass of 291,04 g/mol and a density of 1,87 g/cm³, with CAS number 10026-22-9 and EG number 233-402-1. This hydrated nitrate is widely used as a cobalt source in catalyst preparation, pigment synthesis, electroplating baths and wet-chemical analysis where a defined Co(II) reagent is required. The material is Offered from manufacturer Carl ROTH, the grade meets common p.a. and ACS expectations for routine quality-control and research applications. Its combination of documented purity, clear identity data and practical pack size makes it a reliable choice for laboratories needing a consistent cobalt(II) nitrate hexahydrate reagent for synthesis, standards preparation and general inorganic chemistry workflows.
