Propyl-phenyl-hydrogenphosphit, also known as propylphenylphosphine, is an organophosphorus compound with the chemical formula C9H13P. It is a colorless liquid at room temperature and is derived from the combination of a propyl group (C3H7), a phenyl group (C6H5), and a hydrogen phosphide (PH). Propyl-phenyl-hydrogenphosphit is primarily used as a ligand in organometallic chemistry, particularly in the synthesis of transition metal complexes, and as a reagent in various chemical reactions. Due to its phosphorus-hydrogen bond, it can act as a reducing agent and is also used in the preparation of other organophosphorus compounds. Propyl-phenyl-hydrogenphosphit is sensitive to air and moisture, and it should be handled with care due to its potential toxicity and reactivity.
The CAS Registry Mumber 1559-19-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 9 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1559-19: (6*1)+(5*5)+(4*5)+(3*9)+(2*1)+(1*9)=89 89 % 10 = 9 So 1559-19-9 is a valid CAS Registry Number.
