The Arrhenius equation was used in a study to calculate activation energies for the chlorination of four parent parabens (methyl-, ethyl-, propyl-, and butylparaben) and was found to range from 36–47 kJ/mol. [21] In another study, tap water at 20 °C (68 °F) containing 50–200 μM free chlorine was spiked with 0.5 μM propylparaben and the ...
The numbers are included in the name to avoid ambiguity about the position of the groups, and "tri" indicates that there are three identical methyl groups. If one of the methyl groups attached to the third carbon atom were instead an ethyl group, then the name would be 3-ethyl-2,3-dimethylpentane.
Meprobamate—marketed as Miltown by Wallace Laboratories and Equanil by Wyeth, among others—is a carbamate derivative used as an anxiolytic drug. It was the best-selling minor tranquilizer for a time, but has largely been replaced by the benzodiazepines due to their wider therapeutic index (lower risk of toxicity at therapeutically prescribed doses) and lower incidence of serious side effects.

Pentylone is a stimulant developed in the 1960s. [3] It is a substituted cathinone that has been identified in some samples of powders sold as "NRG-1", along with varying blends of other cathinone derivatives including flephedrone, MDPBP, MDPV, and 4-MePPP.
Butylparaben, or butyl p-hydroxybenzoate, is an organic compound with the formula C 4 H 9 O 2 CC 6 H 4 OH. [1] It is a white solid that is soluble in organic solvents. It has proven to be a highly successful antimicrobial preservative in cosmetics. [2] It is also used in medication suspensions, and as a flavoring additive in food.
Vermont, a state with a long waiting list for medically based drug treatment, suspended a doctor’s license over incomplete paperwork. As doctors face scrutiny from the DEA, states have imposed even greater regulations severely limiting access to the medications, according to a 2014 report commissioned by the federal agency SAMHSA.
Urethane (ethyl carbamate) was once produced commercially in the United States as a chemotherapy agent and for other medicinal purposes. It was found to be toxic and largely ineffective. [27] It is occasionally used in veterinary medicine in combination with other drugs to produce anesthesia. [28]
