<p>2-(2-Ethoxyphenoxy)ethyl bromide is a substance that is found as an impurity in the drug sulphonamide. It has been shown to be an optical isomer of methanol and ethanol, which have base form. The substance crystallizes in the form of white needles and its base form is tamsulosin hydrochloride. It has been used as a reagent for organic chemistry reactions, such as recrystallization, and as an impurity in organic solvents.</p>

<p>O-Ethoxybenzoyl chloride is a pesticide that belongs to the group of sildenafil. It inhibits the activity of prolyl endopeptidase, an enzyme that degrades the peptide hormone vasoactive intestinal polypeptide (VIP). This inhibition prevents degradation of VIP, which is important for the regulation of blood vessel tone. The compound has been shown to be effective against Sclerotinia sclerotiorum and Claviceps purpurea. O-Ethoxybenzoyl chloride has been shown to have a high level of tolerance in plants and animals. It also has been found to be safe for humans with its low toxicity levels and low acute toxicity. It is not classified as hazardous by the World Health Organization (WHO).</p>
