Clopidogrel Carboxylic Acid Hydrochloride

Clopidogrel Carboxylic Acid Hydrochloride
(S)-α-(2-Chlorophenyl)-6,7-dihydrothieno[3,2-c]pyridine-5(4H)-acetic Acid Hydrochloride; SR 26334 Hydrochloride
Clopidogrel  is an antithrombic compound whose active metabolite is a selective, irreversible antagonist of the platelet purinergic P2Y12 receptor 1,2 Clopidogrel inhibits ADP-induced platelet aggregation ex vivo and functions as a prodrug whereupon biotransformation to its active thiol metabolite via CYP2C19 in the liver enables its anti-aggregating activity.3 An estimated 15% of administered clopidogrel is metabolized by CYP2C19 to the thiol metabolite. 
Clopidogrel carboxylic acid is a major inactive metabolite of clopidogrel. Most (85%) of circulating clopidogrel is hydrolyzed by esterases to this carboxylic acid form. This inactive metabolite can be used as a reference standard for quantitative analysis of clopidogrel metabolism.

Preparation of mercuric acetate solution 10 percent

Pour about 75 ml of Glacial Acetic Acid into a 250 ml capacity beaker. Weigh 10.0 grams of Mercuric Acetate LR and transfer slowly, into above-said beaker, though it‘s sidewalls, while gentle mixing by using a glass rod. Transfer prepared solution into a 100 ml volumetric flask, by using a glass funnel. Rinse the beaker and funnel with few ml of Glacial Acetic Acid, and allow to add into the contents of volumetric flask. Make up the volumetric flask to mark with Glacial Acetic Acid , remove the funnel, keep the lid to close the volumetric flask and shake gently to mix the solution. Transfer the prepared solution into a suitable container and label with all necessary details. The resultant solution is having the concentration of 10.0% w/v.
