The compound has a chiral center and exists in two enantiomeric forms, with the (R)-(-) enantiomer being the more commonly used form. It is a colorless to light yellow liquid with a faint, sweet odor, and it is soluble in most organic solvents. (R)-(-)-2-(P-TOLUENESULFONATE)-1,2-PROPANOL is widely utilized in various industries, including pharmaceuticals and agrochemicals, due to its ability to separate and purify enantiomers, which are often important in the production of pharmaceuticals and other fine chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 69891-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,9 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69891-44:
(7*6)+(6*9)+(5*8)+(4*9)+(3*1)+(2*4)+(1*4)=187
187 % 10 = 7
So 69891-44-7 is a valid CAS Registry Number.

Highly Regioselective and Stereospecific Functionalization of 1,2-Proanediol with Trimethyl(X)silanes Employing the 1,3,2λ5-Dioxaphospholane Methodology
Mathieu-Pelta, Isabel,Evans, Slayton A.
, p. 3409 - 3413 (2007/10/02)
The regioselective ring opening of (S)-4-methyl-2,2,2-triphenyl-1,3,2λ5-dioxaphospholanes (2) was initiated with several trimethylsilyl reagents (Me3SiX: X = PhS, I, Br; Cl, CN, and N3) to afford the regioisomeric (silyloxy)phosphonium salts.A stereospecific extrusion of triphenylphosphine oxide from these oxyphosphonium salts gave predominatly the thermodynamically less stable C-2-X-substituted derivatives with nearly complete inversion of stereochemistry at the C-2 stereogenic center (i.e., X = PhS).
