What is a general use for halogenated phenols?

anti-septic solutions use halogenated phenols \nhalogenated phenols are less reactive than general phenols

It does apply loosely to other halides, but Cl and Fl are considerably more reactive.  Br and especially I have more significant steric hindrances to overcome.\n\nSee the link below to see where Markownikoff gort his idea.

Halogens in general have antiseptic properties.  Think about chlorine!

Here are some of the more common applications of these techniques:\n\nGas Chromatography - Flame Ionization Detector, also called GC-FID.  This method is used to analyze mixtures of substances which have an appreciable vapor pressure and are capable of burning.  GC-FID is often used to periodically check a reaction mixture to see how far a particular reaction has gone.  It is also used to check for purity of the final product and to check for undesirable impurities.  \n\nHPLC can also be used in a similar way to GC-FID except that it is better at analysis of non-volatile compounds.  HPLC is often used to analyze the final purity of a product, or to analyze the concentration of a pharaceutical product in a physiological sample (blood, plasma, urine, etc).  \n\nUV-vis is good at measuring the concentration of a UV-absorbing compound in a matrix which contains no other UV-absorbers.  Sometimes you can take your final product and dissolve in non-uv absorbing solvent and measure the UV-vis absorbance to determine concentration or assay.\n\nThe above are just some of the more common uses.  There are many more uses for these techniques in the Pharma industry.

i think you've named your compound incorrectly.  The phenol is already in the one position, so the propyl can't be.  I can only assume you mean 2-propylphenol.\n\nIf you mean 2-propyl phenol then there are a couple of ways.\n\nProtect your phenol with the MOM or MEM group by using phenol and MOM-Cl or MEM-Cl.  Treat with butyl lithium at -78oC to promote an ortho-directed lithiation.  MOM and MEM ethers work better than others as they allow additional co-ordination and stability points for your lithium through the additional oxygen lone-pairs, stabilising the phenyl lithium formed.  Treat with propanal.  The phenyl lithium will nucelophilically attack your aldehyde to give you a secondary alcohol.  De-hydrate the alcohol under acidic conditions to give the alkene, hydrogenate over Pd/C to give your alkane.  Alternatively you can de-hydrate by mesylating your alcohol and treating with a base such as TEA or DIPEA, reflux sometimes helps.  Finally remove your MEM or MOM protecting group using acid to release your desired 2-propylphenol.\n\nI hope this helps.

while the answer above is right i thought i'd add to it.\n\nThe reason you can't do a direct tri bromonation is that once you add on a Br, two add on another two is a very, very slow reaction.  Therefore you need to add in an activating group.  CH3 is a good activating group, but NH3 is better, a bit more time consuming to attach to the benzene but you won't have to heat your reaction up as much later.\n\nIf you use NH3 this will create 1-amino-2,4,6-tribromobenzene, then you can hydrolyse to get rid of the NH3.  In the lab i do it that way, but you can also do it the above way.

Use a retro synethic method.\n\nTarget Molecule <-----  1,2-dibromo- 1,3-dibenzylpropane   (M2) (use 3eq. of NaNH3 in ammonia)\nM2 <---- 1,3-diphenyl-1-propene (M3) (use Br2 in CCl4)\nM3 <---- 1,3-diphenyl-2-propanol (M4) (use KOH/EtOH)\nM4 <---- 2-phenylethanal (M5) + benzyl bromide (M6) (Grignard rxn)\nM5 <---- 2-phenylethanol (M7) + Cr6+ (use chromic acid)\nM7 <----  Styrene (starting material #1) + i)BF3 ii) H2O2, HO-, H2O (anti-Markovnikov hydroboration)\nM6 <---- Benzyl alcohol (starting material #2) + Mg(s) in Et2O (make your Grignard to be condensed in a step later on)\n\nNow, you do the connections. Note my nomenclature is rusty and I'm not 100% sure about the phenyl nomenclature as Benzen side chains to a higher priority parent chain.

There are many you could choose.  These may not be the most efficient, but I'm just going with initial thoughts here.\n\n1.  Aniline -> benzamide\nDiazotise the aniline and trap out with CO2 to form benzoic acid, then make an amide.  Probably easiest way is to make the acid chloride with (COCl)2 and then treat with NH3.\n\n2. Bromobenzene -> 1-phenylethanol\nForm phenylmagnesium bromide by treating bromobenzene with magnesium in diethyl ether, and react with ethanal.\n\n3. Butanal -> 1-chloropropane\nMany ways to do this, none of them nice.\n\nReduce butanal to butanol, de-hydrate, perform a reductive oxonolysis to give 1-propanol and then do a chloro-dehydroxylation with SOCl2 or something like that.\n\nAlterantively you could oxidise and do a Barton-Crich de-carboxylation and trap out the radical with NCS, although this method may not be too successful.\n\nHope these quick ideas help.

At high pH values (>10), the Hydroxide ion in solution takes protons from the phenolphthalein indicator, forming an ion and water.  The -2 ionic form of phenolphthalein then rearranges the electronic structure to form the characteristic pink color.\n\nSee the wikipedia article for more.

Tetrachlorophthalic Anhydride is what you mean-two words.  Its used as a flame retardant in epoxy resin, plastics, paper and textiles. It is also used as an intermediate to produce pharmaceuticals, dyes, plasticizers, and other organic compounds.

There are many things that can be used including alum and ferric salts.  The best thing and the first thing I fix at a plant is to make sure the rest of the treatment system is working properly.  90% of the time, that alone will cause a decrease in the use of polymer and allows the use of a mineral salt treatment.  I do this work around the world.  The main use of the organic polymers for coagulation is simplicity of operation, cost, but mostly good salemanship.  You can cover up many bad operations by adding more polymer.\n\nGum will probably not work.  There are many things tried, but most of them do not overcome the good operations and cost issues.
