Claisen Condensation is a Carbon-Carbon bond-forming reaction between two Esters, where one Ester acts as a Carbonyl Compound.

We currently perform Cryogenic Reactions at temperatures ranging from -30°C to -40°C, with plans to reach temperatures between -50°C and -60°C.

Cyclization is a chemical reaction where one or more rings are formed in a molecule, utilizing reagents such as Acetic Anhydride, Urea, Formic Acid, Glycol (for Ketal Reactions), and Glycerol.

It is a chemical process involving the removal of nitro groups (-NO₂) from organic compounds using chlorine gas or a chlorinating agent.

We manufacture on a multi-thousand-ton scale using Continuous processes and are among the few companies globally with these capabilities, including:

Esterification involves the formation of an Ester from a Carboxylic Acid and an Alcohol, typically in the presence of an Acid Catalyst. We perform this reaction under both Batch and Continuous Processes.

We conduct Etherification on a multi-thousand-ton scale. This includes Ullmann Etherification, where Ethers are synthesized from Aryl Halides in the presence of a Copper Catalyst and a Base.

Our Fluorination capabilities include:

Grignard reagents are organometallic compounds used in organic synthesis. These reagents are highly versatile and widely employed for forming carbon-carbon bonds through nucleophilic addition reactions. Anupam Rasayan performs Grignard chemistry and has commercialized Grignard products using magnesium powder, strips and turning. We have expertise in handling acetone, THF and benzonitrile solvents in this reaction.

The Hofmann Rearrangement involves the reaction of an Amide with a Halogen (Chlorine or Bromine) in a strongly basic medium, converting the Amide into an Amine.

We offer Hydrogenation capabilities across a range of compounds and conditions, including Acidic Hydrogenation of Fluorinated Compounds.

The ketone reduction involves the conversion of the carbonyl group to the corresponding alkane using reducing agents like sodium borohydride, triethyl silane, and tetramethyl disiloxane, as well as Lewis acids such as aluminium chloride, boron trifluoride-THF, and boron trifluoride-diethyl ether.

It is a modification of aldol condensation and an addition of active hydrogen compound to the carbonyl group compound followed by dehydration.

Nitration is a process that adds a Nitro group to an organic compound. We perform Nitration on a multi-thousand-ton scale using both Batch and Continuous processes, focusing on minimal effluent generation and selectivity. Our Nitration capabilities include:

We perform Chemical Oxidation, Air Oxidation and Photo Chemical Oxidation.

Photo Cycloaddition is a photochemical reaction in which two or more unsaturated molecules combine to form a cyclic product. We have developed this reaction using Flow Photochemistry.

We have a commercial facility for performing photochemical reactions in continuous mode, including reactions such as Photo Chlorination, Photo Bromination and Photo Oxidation.

The Pinner Reaction is an Acid-Catalyzed reaction where a Nitrile reacts with an Alcohol to form an Imino Ester Salt.

The Sandmeyer Reaction involves converting Aryl Diazonium Salts into various functional groups, such as halides, through substitution reactions.

It is a novel process utilizing schiff base, enabling us to perform two hydrogenation stages into a single step in-situ.

It is derived from asymmetrical & substituted diarylamines.

Triazole condensation refers to a process of synthesizing compounds containing triazole rings. Due to their diverse biological and physicochemical properties, triazole derivatives are widely found in pharmaceuticals, agrochemicals, and materials science. Anupam Rasayan has superior competence in handling hexane and dimethyl sulfide solvents in this reaction.

We use triphosgene as a reactant for chlorination & ring closing.

The Vilsmeier-Haack Reaction involves the reaction of a Substituted Formamide with Phosphorus Oxychloride and Arene to form Aldehyde or Ketone.
