CAS 100-63-0 — Phenylhydrazine

Phenylhydrazine (CAS 100-63-0) is a colorless to pale yellow oily liquid with the molecular formula C6H5NHNH2 and a molecular weight of 108.14 g/mol. It is primarily used as a reagent in organic synthesis, particularly for the formation of hydrazones and osazones, and historically in the identification of sugars. It requires careful handling due to its hazardous nature, including toxicity and flammability. Store at ambient temperatures in a well-ventilated area, away from sources of ignition. Molekula supplies phenylhydrazine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
