INTRODUCTION
Pyrophosphoryl Tetrachloride is a colorless fuming corrosive liquid .It consists of a pyrophosphate (a molecule with a P-O-P bond) group, where one phosphorus atom is bonded to four chlorine atoms and the other is bonded to three chlorine atoms. It is a reactive chemical compound and should be handled with care. Commonly used in the synthesis of other phosphorus-containing compounds and as a chlorinating agent in organic chemistry
Manufacture
It is manufactured by chlorination of Phosphorous Pentoxide with Phosphorous Trichloride followed by distillation process.

2-(tert-Butyl amino)ethyl methacrylate (TBAEMA) is a functional methacrylate monomer that contains a secondary amine group and a hydrophobic tert-butyl moiety, giving it excellent versatility in pH-responsive and adhesion-enhancing polymer systems.
It is valued in printing ink formulations for its ability to enhance adhesion, flexibility, and surface interaction.
Commonly known as potassium bis(fluorosulfonyl)imide (KFSI), the compound has a three-carbon backbone bearing six fluorine atoms and two sulfonimide (-SO₂F) groups. The molecule’s architecture lends it both high chemical stability and useful reactivity. Because of its excellent ionic conductivity and thermal / electrochemical stability, it finds use in advanced electrolyte formulations—for example in lithium-ion and next-generation batteries, in ionic liquids, and in other electrochemical systems.
Colchicine is a naturally occurring alkaloid obtained primarily from the autumn crocus (Colchicum autumnale) and related species. It has been used in medicine for centuries, especially for the treatment of gout and Familial Mediterranean Fever. In modern medicine, Colchicine is valued also in conditions like pericarditis, Behçet’s disease, and certain dermatological and cardiac disorders.
1-Butylimidazole is a versatile organic heterocyclic compound belonging to the imidazole family, where a butyl group (–CH₂–CH₂–CH₂–CH₃) is attached to the nitrogen atom at the 1-position of the imidazole ring. Its applications span organic synthesis, materials science, and bioactive compound development due to its tunable physicochemical properties and structural versatility.
Atropine sulfate monohydrate is a chemical compound, specifically a salt of atropine and sulfuric acid, with one water molecule (monohydrate) attached. It is commonly used as a medication and in research due to its anticholinergic properties, meaning it blocks the effects of acetylcholine at muscarinic receptors.
4-Aminobenzoic acid, commonly abbreviated as PABA, is an aromatic amine and carboxylic acid compound. It consists of a benzene ring substituted with an amino group (–NH₂) in the para position to a carboxylic acid group (–COOH).
2-Amino-5-Nitrophenol (5-NAP) is an organic compound with the molecular formula C₆H₆N₂O₃. It is a substituted phenol with both an amino group (-NH₂) and a nitro group (-NO₂) attached to a benzene ring, along with a hydroxyl group (-OH).
Pongamol is a naturally occurring flavonoid primarily extracted from the seeds and leaves of the Pongamia pinnata tree (also known as Karanja tree), native to South and Southeast Asia. It is a cream-colored compound that belongs to the flavonoid family and is known for its antioxidant, anti-inflammatory, antimicrobial, and pesticidal properties. It is one of the key bioactive constituents of Pongamia oil.
Biobased Ethyl Acetate is an environmentally friendly solvent made from renewable sources like bioethanol extracted from sugarcane, corn, and other forms of biomass. Unlike traditional ethyl acetate, which is typically derived from fossil fuels, this green alternative shares the same chemical structure (C₄H₈O₂) and functional performance—offering comparable versatility with a significantly lower environmental footprint.
