5. anticholinergic, treatment of motion sickness
Production Methods
Maleic anhydride is treated with 2-ethylhexanol to produce dioctyl
maleate, which is then reacted with sodium bisulfite.

Fire Hazard
Behavior in Fire: Causes foaming and spreading of water. Assists in putting out fires by water.

Pharmaceutical Applications
Docusate sodium and docusate salts are widely used as anionic
surfactants in pharmaceutical formulations. Docusate sodium is
mainly used in capsule and direct-compression tablet formulations
to assist in wetting and dissolution.
Safety Profile
Poison by intravenous
route. Moderately toxic by ingestion and
intraperitoneal routes. A skin and severe eye
irritant. See also ESTERS. When heated to
decomposition it emits toxic fumes of SOx
and Na2O.
Safety
Docusate salts are used in oral formulations as therapeutic agents
for their fecal softening and laxative properties. As a laxative in
adults, up to 500mg of docusate sodium is administered daily in
divided doses; in children over 6 months old, up to 75 mg in divided
doses is used. The quantity of docusate sodium used as an excipient
in oral formulations should therefore be controlled to avoid
unintended laxative effects. Adverse effects associated with
docusate sodium include diarrhea, nausea, vomiting, abdominal
cramps, and skin rashes. As with the chronic use of laxatives, the
excessive use of docusate sodium may produce hypomagnesemia.
Docusate salts are absorbed from the gastrointestinal tract and
excreted in bile; they may cause alteration of the gastrointestinal
epithelium. The gastrointestinal or hepatic absorption of other
drugs may also be affected by docusate salts, enhancing activity and
possibly toxicity. Docusate sodium should not be administered with
mineral oil as it may increase the absorption of the oil.
LD50 (mouse, IV): 0.06 g/kg
LD50 (mouse, oral): 2.64 g/kg
LD50 (rat, IP): 0.59 g/kg
LD50 (rat, oral): 1.9 g/kg
Solubility in organics
Dioctyl sodium sulfosuccinate (DSS) is the dioctyl ester of sodium sulfosuccinate (bis-2-ethyl-hexyl sodium sulfosuccinate). It dissolves slowly in water; at 25°C to the extent of 1.5 gm/100cc; at 70°C, 5.5 gm/100cc. It dissolves in oils, hydrocarbons, fats and waxs by heating above 75°C and remains in solution when cooled to room temperature. At room temperature, it is readily soluble in most organic solvents, both polar and non-polar. soluble in carbon tetrachloride, petroleum ether, naphtha, xylene, dibutyl phthalate, liquid petroleum, acetone, alcohol, vegetable oils.
storage
Docusate sodium is stable in the solid state when stored at room
temperature. Dilute aqueous solutions of docusate sodium between
pH 1–10 are stable at room temperature. However, at very low pH
(<1) and very high pH (>10) docusate sodium solutions are subject
to hydrolysis.
The solid material is hygroscopic and should be stored in an airtight container in a cool, dry place.
Purification Methods
Dissolve it in MeOH and the inorganic salts which precipitate are filtered off. Water is added and the solution is extracted several times with hexane. The residue is evaporated to one-fifth its original volume, *benzene is added and azeotropic distillation is continued until no water remains. The solvent is evaporated. The white residual solid is crushed and dried in vacuo over P2O5 for 48hours [El Seoud & Fendler J Chem Soc, Faraday Trans 1 71 452 1975]. [Beilstein 4 IV 114.] It solubilises major myelin trans membrane proteolipids, and forms reverse micelles in hydrocarbon solvents.
Incompatibilities
Electrolytes, e.g. 3% sodium chloride, added to aqueous solutions
of docusate sodium can cause turbidity. However, docusate
sodium possesses greater tolerance to calcium, magnesium, and
other polyvalent ions than do some other surfactants. Docusate
sodium is incompatible with acids at pH < 1 and with alkalis at pH
> 10.
Regulatory Status
GRAS listed. Included in the FDA Inactive Ingredients Database
(IM injections; oral capsules, suspensions, and tablets; also topical
formulations). Included in nonparenteral medicines licensed in the
UK. Included in the Canadian List of Acceptable Non-medicinal
Ingredients.
Check Digit Verification of cas no
The CAS Registry Mumber 577-11-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 577-11:
(5*5)+(4*7)+(3*7)+(2*1)+(1*1)=77
77 % 10 = 7
So 577-11-7 is a valid CAS Registry Number.

Dual catalytic activity of amberlyst-15 in the large-scale and sustainable synthesis of dioctyl sodium sulfosuccinate (DOSS)
Fateh, Davod S.,Moghadam, Seyed M. M.,Salehi, Samie,Tarin, Mojtaba
, p. 555 - 559 (2020/07/17)
Dioctyl sodium sulfosuccinate (DOSS) as a unique material both as a drug and surfactant was synthesized by a facile and economical synthetic method. In this project, Amberlyst-15 was select-ed as a heterogeneous recyclable bronsted solid acid for this synthesis both in the esterification of ma-leic anhydride and sulfonation of dioctyl maleate (DOM) ester. This catalyst was easily recovered and reused at least for 13 consecutive cycles without a significant loss in the catalytic activity. In this paper, we wish to uncover a catalytic approach for the synthesis of DOSS through a recyclable, easily recov-erable, and commercially available catalyst, namely Amberlyst 15, under mild conditions.
