Description

Chloroacetaldehyde is the organic compound with the formula ClCH2CHO. Like some related compounds, it is highly electrophilic reagent and a potentially dangerous alkylating agent. The compound is not normally encountered in the anhydrous form, but rather as the hydrate (acetal), ClCH2CH(OH)2. Chloroacetaldehyde is a useful intermediate in the synthesis, e.g. of 2-aminothiazole or many pharmaceutical compounds. Another use is to facilitate bark removal from tree trunks.

4.3 Indication of immediate medical attention and special treatment needed, if necessary

/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aldehydes and Related Compounds/

12.2 Persistence and degradability

PURE CULTURE: Pseudomonas CE1r, isolated from soil, degraded 2-chloroethanol via 2-chloroacetaldehyde and 2-chloroacetate to glycollic acid(1).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for chloroacetaldehyde(SRC), using an estimated log Kow of 0.09(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 chloroacetaldehyde can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that chloroacetaldehyde is expected to have very high mobility in soil.

12.5 Other adverse effects
