13587-50-3 Usage
General Description
(~3~H_1_)phosphane, also known as phosphine or PH3, is a colorless, flammable, and toxic gas with a distinct odor similar to garlic or decaying fish. It is composed of one phosphorus atom bonded to three hydrogen atoms. Phosphine is a highly reactive compound and is used in various industrial applications, including as a fumigant for grain and a precursor for the production of other chemicals such as phosphorus trichloride and organophosphorus compounds. It is also an important reagent in organic chemistry, commonly used as a reducing agent and as a ligand in coordination chemistry. However, due to its toxicity and flammability, phosphine must be handled with caution and proper safety measures.
Check Digit Verification of cas no
The CAS Registry Mumber 13587-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,8 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13587-50:
(7*1)+(6*3)+(5*5)+(4*8)+(3*7)+(2*5)+(1*0)=113
113 % 10 = 3
So 13587-50-3 is a valid CAS Registry Number.

The ground vibrational states of PH2D and PHD2
Ulenikov,Bürger,Jerzembeck,Onopenko,Bekhtereva,Petrunina
, p. 225 - 237 (2007/10/03)
The high resolution (2.3-3.1 × 10-3 cm-1) Far infrared Fourier transform spectrum of PH2D and PHD2 was recorded in the 20-160 cm-1 region. Assignments were made using a specially developed computer-assisted automatic 'two pair transition' method. Altogether, 1300 and 590 infrared transitions of the PHD2 and PH2D species, respectively, were fitted together with appropriately weighted microwave transitions to derive the rotational and centrifugal distortion parameters up to eighth order of the ground vibrational states of both molecules. The parameters obtained from these fits reproduce the microwave transitions with accuracies close to experimental uncertainties. A few of microwave transitions were shown to be blended, or misassigned. The rms deviations for the infrared data are 1.01 × 10-4 and 1.05 × 10-4 cm-1 for PH2D and PHD2, respectively, which is also close to the experimental uncertainty.
