Medical Definition of KILOGRAM. 1. : the base unit of mass in the International System of Units that is equal to the mass of a prototype agreed upon by international convention and that is nearly equal to the mass of 1000 cubic centimeters of water at the temperature of its maximum density.2.. : the base unit of mass in the International System of Units that is equal to the mass of a prototype agreed upon by international convention and that is nearly equal to the mass of 1000 cubic centimeters of water at the temperature of its maximum density. 2.
Discard the water layer, which contains the aspirin or acetominophen) and evaporate the chloroform layer to dryness under gentle heat. The result is codeine base, a white crystalline powder. Combine 20 mL pyridine and 25 mL conc. HCl in a beaker and heat strongly to 190C to drive off any water.
Codeine sulfate is an opioid analgesic, related to morphine, but with less potent analgesic properties. Chemically, codeine is Morphinan-6-ol,7,8-didehydro-4,5-epoxy-3-methoxy-17-methyl-(5Î±,6Î±)-, sulfate (2:1) (salt), trihydrate.Its empirical formula is C 18 H 21 NO 3 and its molecular weight is 299.36.etabolism. About 70-80% of administered dose of codeine is metabolized by conjugation with glucuronic acid to codeine-6glucuronide (C6G) and via O-demethylation to morphine (about 5-10%) and N-demethylation to norcodeine (about 10%) respectively.
