Deuterated chloroform (CDCl₃), also known as chloroform-d, is an isotopologue of chloroform (CHCl₃) in which the hydrogen atom ("H") is replaced with a deuterium (heavy hydrogen) isotope ("D"). Deuterated chloroform is a common solvent used in NMR spectroscopy. Most compounds soluble in dichloromethane are soluble in chloroform, but chloroform is much cheaper than deuterated DCM. The properties of CDCl₃ are virtually identical to those of regular chloroform.
Xylylene diisocyanate composition, polymerizable composition, resin, molded body, optical element, and lens
A xylylene diisocyanate composition includes a xylylene diisocyanate and a specific compound. The specific compound has a peak in a range of chemical shift values of 2.44 ppm to 2.46 ppm based on chloroform in deuterated chloroform when the xylylene diisocyanate composition is mixed with the deuterated chloroform and measured by 1H-NMR measurement.

To provide a resin composition and an adhesive which can suppress bleeding, at least thermosetting. A resin composition comprising: (A) a polymerizable compound having a carbon-carbon double bond, (B) a polythiol compound, (C) a polymerization initiator, and (D) a modified dimethylpolysiloxane satisfying at least one of the following characteristics (a) and (b): (a) an organic substituent containing a COOH group or an OH group is directly bonded to the dimethylpolysiloxane, or is bonded to the dimethylpolysiloxane through a linking group; (b) a signal disappears in deuterated chloroform 1 In the1H NMR spectrum, signals were present in the ranges of 0.3 to -0.3 ppm and 4.4 to 3.2 ppm, and a signal disappeared due to the addition of D2O in the range of 13 to 0 ppm.
