Description

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is a bio-based ethanol and is aligned with the 5th principle of Green Chemistry "Safer Solvents and Auxiliaries" and 7th principle "Use of Renewable Feedstock".

Application

Ethanol may be used as follows:

Preparation of PANI/MnFe2O4 nanocomposite thin films to study their optical properties and capacitive behaviors
Preparation of Andrographis paniculata extracts for HPLC fingerprint analysis to study their composition and biological activities
As a mobile phase for the HPLC separation of paritaprevir, ritonavir, and ombitasvir in pharmaceutical dosage forms
To evaluate the anti-solvent effects of three solvents in order to quantify the paracetamol active pharmaceutical ingredient (API) and its two impurities precipitating out during washing
