    摘要: A process for the preparation of isosulfan blue (Active Pharmaceutical Ingredient) is provided. A process is also provided for preparation of the intermediate, 2-chlorobenzaldehyde-5-sulfonic acid, sodium salt of formula (2), used in the preparation thereof and a procedure for the isolation of benzaldehyde-2,5-disulfonic acid, di-sodium salt of the formula (3). Also provided is a process for the preparation of an isoleuco acid of formula (4), which upon mild oxidation gives rise to isosulfan blue of pharmaceutical grade which can be used for preparation of pharmaceutical formulations. The isolation and purification procedures provided in the process provide substantially pure isosulfan blue with HPLC purity 99.5% or greater.

    摘要: Exploitation of suitably functionalized heterocyclic molecules, in the design and synthesis of Fluorescence Resonance Energy Transfer (FRET) cassettes and their corresponding dideoxynucleotide terminators culminated into efficient reagents for DNA sequencing. Additionally, these FRET cassettes/terminators, of the present invention, derived from different classes of heterocyclic systems have high potential to be used for general labelling of biological molecules to generate highly sensitized signals. Their preparation, energy transfer efficiency, and use as labels, specifically, in DNA sequencing reactions is disclosed.

    摘要: A process for preparation of protriptyline hydrochloride from 5-dihydrobenzocycloheptatriene of formula (1) by coupling with chloropropyl alcohol in the presence of excess n-butyl Lithium in tetrahydrofuran under inert atmosphere, followed by preparation of mesylate derivative of formula (3) and finally the nucleophilic displacement of the mesylate group by reacting methylamine solution in methanol to give protriptyline free base of the formula (4). Also the present process reveals the hydrochloride salt formation and purification of the same to give pure pharmaceutical grade protriptyline hydrochloride with impurities less than 0.1% w/w.
