SECTION 10: Stability and reactivity

10.1Reactivity

no data available

10.2Chemical stability

Tablets have expiration date of 3 yr following date of mfr

10.3Possibility of hazardous reactions

MEBENDAZOLE is a carbamate ester-amine. Amines behave as chemical bases. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

no data available

12.3Bioaccumulative potential

An estimated BCF of 83 was calculated for mebendazole(SRC), using a log Kow of 2.83(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC), provided the compound is not metabolized by the organism(SRC).

12.4Mobility in soil

The Koc of mebendazole is estimated as 830(SRC), using a log Kow of 2.83(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that mebendazole is expected to have low mobility in soil.

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal 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.
