SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on contact with strong acids. This produces toxic and irritating fumes including nitrogen oxides and sulfur oxides. Reacts violently with strong oxidants. This generates fire hazard.
Chemical stability
Readily oxidized by sunlight or when in presence of finely divided inert carrier, acquiring greenish-brown tint
Possibility of hazardous reactions
ALTHOUGH PHENOTHIAZINE OXIDIZES FAIRLY EASILY WHEN IT IS EXPOSED TO AIR, RISK OF FIRE IS NOT HIGH.PHENOTHIAZINE is slowly decomposed by sunlight. (NTP, 1992). Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.
Conditions to avoid
no data available
Incompatible materials
STABILITY: This compound is slowly decomposed by sunlight. (NTP, 1992)
Hazardous decomposition products
If involved in fire, phenothiazine produces highly toxic sulfur & nitrogen oxides, which are dangerous lung irritants.

STOT-repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged exposure may cause skin photosensitization. The substance when ingested may have effects on the blood and nervous system.
Aspiration hazard
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Oncorhynchus mykiss (previous name: Salmo gairdneri) - 70.7 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 11.92 mg/L - 48 h.
- Toxicity to algae: EC50 - Desmodesmus subspicatus (previous name: Scenedesmus subspicatus) - > 100 mg/L - 72 h.
- Toxicity to microorganisms: IC10 - activated sludge of a predominantly domestic sewage - > 100 mg/L - 30 min. Remarks:Respiration rate.
Persistence and degradability
A four-week biodegradation study using 30 mg/l sludge and a phenothiazine concentration of 100 mg/l gave a theoretical BOD of 0%(1).
Bioaccumulative potential
An estimated BCF value of 840 was calculated for phenothiazine(SRC), using an experimental log Kow of 4.15(1) and a recommended regression-derived equation(2). An eight-week bioconcentration study using carp and phenothiazine concentrations of 20 and 2 ug/l gave BCF values of 127-660 and 180-528, respectively(4). According to a classification scheme(3), these BCF values suggest that bioconcentration in aquatic organisms is high(SRC).
Mobility in soil
The Koc of phenothiazine is estimated as approximately 4300(SRC), using an experimental log Kow of 4.15(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that phenothiazine has slight mobility in soil(SRC). The adsorptivity of phenothiazine is expected to be sensitive to pH since phenothiazine is a base with a pKa of 2.52(4).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
