density: 0.944 g/ml; grade: for molecular biolog Technical Inquries: For product support/troubleshooting, please email us your inquiry at: tech@biobasic.co I was working on my chem lab, this question occurred to me. Water and dichloromethane are both polar molecule. However, dichloromethane is able to mix with alcohols much better than water. Is there a polarity difference that caused the miscibility to be different? I was working on my chem lab, this. Basis: Following U.S. EPA (2005) Guidelines for Carcinogen Risk Assessment, dichloromethane is likely to be carcinogenic in humans, based predominantly on evidence of carcinogenicity at two sites in 2-year bioassays in male and female B6C3F1 mice (liver and lung tumors) with inhalation exposure (NTP, 1986) and at one site in male B6C3F1 mice (liver tumors) with drinking water exposure. For instance, if the target compound was the base in the system, the extraction with HCl should be performed first. Whatever remains in the organic layer is not of interest anymore afterwards, unless one of the other compounds has to be isolated from this layer as well
