An alternative synthesis starts with the ethyl ester of 4-hydroxybenzoic acid, which chlorinates at the positions flanking the phenolic center. Ester hydrolysis followed by decarboxylation affords 2,6-dichlorophenol.

A study of house dust in the U.S. found that over 96% of samples collected between 2002 and 2007 contained TDCPP at an average concentration of over 1.8 ppm, while the highest was over 56 ppm. [5] TDCPP was also detected in 99% of dust samples collected in 2009 in the Boston area from offices, homes, and vehicles.
3,4-Epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate (ECC) is a cycloaliphatic epoxy resin which is used in many industrial applications. It reacts by cationic polymerization using thermolatent photoinitiators to form crosslinked insoluble thermosets .
Stereoisomers and racemic mixtures are assigned discrete CAS Registry Numbers: L-epinephrine has 51-43-4, D-epinephrine has 150-05-0, and racemic DL-epinephrine has 329-65-7 Different phases do not receive different CAS RNs (liquid water and ice both have 7732-18-5), but different crystal structures do ( carbon in general is 7440-44-0, graphite ...
The two highest doses used in this study were 1.0 and 6.0 mg per cubic meter for 6 hours each day, 5 days each week for 2 years. The duration-adjusted exposure levels for these two high concentrations are equivalent to 11 ppb and 70 ppb, 24 hours/day for two years.
