Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures

Emergency measure - Inhalation: Remove subject to fresh air.  Give artificial respiration if

breathing has stopped.  Seek immediate medical attention.

Emergency measure - Eyes: Wash with copious amounts of water for 15 - 20 minutes. Seek

medical attention if irritation occurs.

Emergency measure - Skin: Remove contaminated clothing and wash affected area with

soap and water for 15 - 20 minutes.

Emergency measure - Ingestion: Rinse mouth thoroughly with water if the subject is

conscious.  Seek immediate medical attention.

Fire-fighting measures

Recommended extinguishing agent: Use agents appropriate to surrounding environment.  Water or

foam are suitable.

Product arising from burning: Not determined experimentally, but may include C0, C02 plus

oxides of nitrogen.

Product determined by test: N

Protective equipment: Full protective clothing, with self-contained breathing

apparatus.

Accidental release measures

Emergency measures in case of spillage: Protective clothing and respirator should be worn (see

2.3.1).  Spilt material should be swept up and placed in a

sealed container (e.g. fibre drum).  Spill area should then

be washed and ventilated.

Handling and storage

Handling: Use only in well-ventilated areas.  Local exhaust

ventilation and careful use are recommended to minimise dust

generation.  Eye protection and gloves should be worn,

together with a suitable respirator approved to EN 136 and

(e.g. North twin cartrige RP12).  Local washing facilities

must be provided.

Storage: Store in sealed containers in a dry area, away from heat

sources.

Stability and reactivity

Danger other than fire: Not known.

Chemical reaction with water: Hydrolysis occurs under alkaline conditions (see 5.2.2) but

this is not a hazardous reaction.

Disposal considerations

Industry - Possibility of recovery/recycling: SQ29,242 is consumed in the drug synthesis reaction in which

it is employed.  Significant residual levels in reactor

effluent are not expected.  No practical means of recovery

or recycling are known.

Industry - Possibility of neutralisation: No chemical neutralisation method is known.

Industry - Possibility of destruction: controlled discharge: Not recommended.

Industry - Possibility of destruction - incineration: Acceptable provided that a closed-cycle incinerator with

scrubbers is employed.  National regulations must be

observed.

Industry - Possibility of destruction - water purification: Not recommended.

Public at large - Possibility of recovery/recycling: SQ29,242 IS NOT INTENDED FOR PUBLIC USE.
