Dimethylamine is a weak base and the pKa of the ammonium CH 3-NH + 2 -CH 3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79). Dimethylamine reacts with acids to form salts, such as dimethylamine hydrochloride, an odorless white solid with a melting point of 171.5 °C.
Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .
The molecular formula C 2 H 7 N (molar mass: 45.07 g/mol, exact mass: 45.0579 u) may refer to: Ethylamine (ethanamine) Dimethylamine (N,N-dimethylamine)
The terms "molecular mass", "molecular weight", and "molar mass" may be used interchangeably in less formal contexts where unit- and quantity-correctness is not needed. The molecular mass is more commonly used when referring to the mass of a single or specific well-defined molecule and less commonly than molecular weight when referring to a ...
1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1] It is typically employed in the 4.0-6.0 pH range. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds.
BMI stands for body mass index. It’s a calculation of your height relatively to your weight, according to the Centers for Disease Control and Prevention (CDC). BMI is generally classified into ...
It is obtained by the reaction of dimethylamine with phosgene in the presence of sodium hydroxide solution followed by extraction with 1,2-dichloroethane. [2] A closely related method involves combining dimethylcarbamoyl chloride with excess dimethylamine Even though the product is contaminated and smelly it may be purified by addition of calcium oxide and subsequent fractional distillation.

A growing body of evidence has shown links between cancer and drinking alcohol. In a warning Friday, U.S. Surgeon General Vivek Murthy said cancer risk increases with the number of drinks, but ...
