CAS No.:110-64-5
Name: 2-Butene-1,4-diol
Details Introduction
TOXICITY DATA with REFERENCE：
Consensus Reports：Reported in EPA TSCA Inventory.
SAFETY PROFILE：
Standards and Recommendations：Purity is determined by gas chromatography. Technical grade butenediol (110-64-5), specified at 95% minimum, is typically 96 to 98% butenediol (110-64-5). The cis isomer is the predominant constituent; 2 to 4% is trans. Principal impurities are butynediol (110-64-5) (specified as 2.0% maximum, typically less than 1%), butanediol, and the 4-hydroxybutyraldehyde acetal of butenediol (110-64-5). Moisture is specified at 0.75% maximum (Karl-Fischer titration). Technical-grade butenediol freezes at about 8 ℃.
