In-tank toilet cleaners (also known as toilet water tablets or drop-in toilet bowl cleaners) are tablets or cartridges that add chemicals to toilet tank water to reduce toilet bowl stains. They are commonly used to prevent toilet bowl stains from calcium, limescale, mold, etc. [1] Most contain chlorine bleach as its main active ingredient, [2 ...
1-Bromo-3-chloropropane is an organohalogen compound with the formula Br(CH 2) 3 Cl. It is a colorless liquid, produced by free-radical addition of hydrogen bromide to allyl chloride. [1] It is used as an alkylating agent to install the –(CH 2) 3 Cl [2] [3] and –(CH 2) 3 – groups. [4] For example, it is a precursor to 4-chlorobutyronitrile.
The intermediate 1-bromo-3-chlorocyclobutane can also be prepared via a modified Hunsdiecker reaction from 3-chlorocyclobutanecarboxylic acid using mercuric oxide and bromine: [4] A synthetic approach to bicyclobutane derivatives involves ring closure of a suitably substituted 2-bromo-1-(chloromethyl)cyclopropane with magnesium in THF.

2 Li + C 4 H 9 X → C 4 H 9 Li + LiX where X = Cl, Br. The lithium for this reaction contains 1-3% sodium. When bromobutane is the precursor, the product is a homogeneous solution, consisting of a mixed cluster containing both LiBr and LiBu. 1-Fluorobutane can be obtained by reacting 1-bromobutane with potassium fluoride in ethylene glycol. [5]
All three have been synthesized by various routes: 1-Bromo-2-chlorobenzene: from 2-chloroaniline, via diazotization followed by a Sandmeyer reaction [1]; 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution [2] [better source needed]
1,2-Dibromo-3-chloropropane (dibromochloropropane), better known as DBCP, is the organic compound with the formula BrCH(CH 2 Br)(CH 2 Cl). It is a dense colorless liquid although commercial samples often appear amber or even brown. It is the active ingredient in the nematicide Nemagon, also known as Fumazone.
Behind the counter at your local gas station, convenience store, or bodega, tucked within the energy shots and flavored cigarillos, are a variety of male enhancement products like Rhino pills. You ...
2C-B-DRAGONFLY (2C-B-DFLY) is a recreational designer drug with psychedelic effects. It can be regarded as the fully aromatic derivative of 2C-B-FLY. 2C-B-DRAGONFLY is stronger than 2C-B or 2C-B-FLY with around 2-3x the potency of 2C-B in animal studies, demonstrating the importance of the fully aromatic benzodifuran ring system for optimum receptor binding at 5-HT 2A, but it is still ...
