Production Methods
Monothioglycerol is prepared by heating an ethanolic solution of 3-
chloro-1,2-propanediol with potassium bisulfide.
Pharmaceutical Applications
Monothioglycerol is used as an antioxidant in pharmaceutical
formulations, mainly in parenteral preparations.Monothioglycerol
is reported to have some antimicrobial activity.It is also
widely used in cosmetic formulations such as depilating agents.
Therapeutically, monothioglycerol has been used in a 0.02%
w/w aqueous solution to stimulate wound healing, and as a 0.1%
w/w jelly in atrophic rhinitis.
Safety Profile
Poison by
intraperitoneal and intravenous routes.
Experimental reproductive effects. Mutation
data reported. Flammable when exposed to
heat or flame; can react with oxidizing
materials. When heated to decomposition it
emits hghly toxic fumes of SOx.
Safety
Monothioglycerol is generally regarded as a relatively nontoxic and
nonirritant material at the concentrations used as a pharmaceutical
excipient. It is used in topical and injectable preparations.
Undiluted monothioglycerol is considered a poison by the IP and
IV routes; it has also been reported to be mutagenic.

Check Digit Verification of cas no
The CAS Registry Mumber 96-27-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 96-27:
(4*9)+(3*6)+(2*2)+(1*7)=65
65 % 10 = 5
So 96-27-5 is a valid CAS Registry Number.

Template effects of vesicles in dynamic covalent chemistry
Bravin, Carlo,Hunter, Christopher A.
, p. 9122 - 9125 (2020/09/17)
Vesicle lipid bilayers have been employed as templates to modulate the product distribution in a dynamic covalent library of Michael adducts formed by mixing a Michael acceptor with thiols. In methanol solution, all possible Michael adducts were obtained in similar amounts. Addition of vesicles to the dynamic covalent library led to the formation of a single major product. The equilibrium constants for formation of the Michael adducts are similar for all of the thiols used in this experiment, and the effect of the vesicles on the composition of the library is attributed to the differential partitioning of the library members between the lipid bilayer and the aqueous solution. The results provide a quantitative approach for exploiting dynamic covalent chemistry within lipid bilayers. This journal is
