10.3 Possibility of hazardous reactions
Moderate, when exposed to heat or flame1-METHOXY-2-PROPANOL is a methoxy alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

12.2 Persistence and degradability
AEROBIC: 1-Methoxy-2-hydroxypropane, present at 100 mg/L, reached 90% of its theoretical BOD in four weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). The aerobic biodegradation of 1-methoxy-2-hydroxypropane was studied in two sandy loam soils; half-lives ranged from <1 day at 0.2 ppm to <7 days at 100 ppm(2). 1-Methoxy-2-propanol was reported to have a half-life of 17.0 days in an OECD 301B Guideline test(3). In a biodegradation test using an APHA method with 1-methoxy-2-propanol, 58% of the theoretical BOD was reached after 20 days(3).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for 1-methoxy-2-hydroxypropane(SRC), using an estimated log Kow of -0.49(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of 1-methoxy-2-hydroxypropane can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-methoxy-2-hydroxypropane is expected to have very high mobility in soil.
12.5 Other adverse effects

13.Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
