75627-12-2 structure

8-Azoniabicyclo(3.2.1)octane, 3-((hydroxyphenylacetyl)oxy)-8,8-dimethyl-, bromide, endo-( -)-, mixt. with neomycin sulfate (salt)

Iupac Name:methyl 2-[3,6-bis(ethylamino)-2,7-dimethyl-1H-xanthen-9-yl]benzoate
CAS No.:75627-12-2
Molecular Weight:430.548
Molecular Formula:C19H15N3O5 (isomer)
Refractive Index
Blue-green hydroscopic powder
Safety and Handling
Skin, Eye, and Respiratory Irritations
Inhalation of dust causes irritation of throat & lung. ... Contact with solutions irritates eyes; contact with solid causes severe eye surface injury & irritation of skin. /Copper acetate monohydrate/
Cleanup Methods
Environmental consideration - land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.
Environmental consideration - water spill: Neutralize with agricultural lime (calcium oxide), crushed limestone (calcium carbonate), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH= 7). Use mechanical dredges or lifts to remove immobilized masses of pollutants & precipitates.
Fire Potential
It is noncombustible.
Grades or purity: technical, 95-99%; reagent, 99%
Other Preventative Measures
If material not involved in fire: Keep material out of water sources & sewers. Build dikes to contain flow as necessary.
Personnel protection: Keep upwind. Avoid breathing vapors or dusts. Wash away any material which may have contacted the body with copious amt of water or soap & water.
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Protective Equipment and Clothing
Inhalation of dust causes irritation of throat & lung. ... Contact with solutions irritates eyes; contact with solid causes severe eye surface injury & irritation of skin. /Copper acetate monohydrate/
Disposal Methods
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
