Science - Biology (-tech,-chem,micro-) / MSDS Labels/Pesticides

English term or phrase: (RS)--cyano-3-phenoxybenzyl (1RS)-cis-trans-3- ...

Please note the whole formula listed below.

This is the compound listed as the active ingredient in a pesticide label. The compound itself is called "Cypermethrin", in Arabic سيبرمثرين. There isn't much more by way of chemical data to go by. The ingredient list looks like this:

Active Ingredient By Wt.
Cypermethrin*: (RS)--cyano-3-phenoxybenzyl (1RS)-cis-trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate........... 11%
Inert Ingredients**.............................… 79%

The unprintable character in the formula is the greek letter (alpha).

Thanks.

After Asker Note:
Yes, me too used to leave them without translation, except some cases, which depends on the client as well.
However, we do our best to reach the optimal performance without inventing from our minds, so i think you did so.
Good Luck

عذراً أخ علاء كنت قد خلدت إلى النوم عندما أرسلت آخر نقاط النقاش
من المؤكد أن راسيم ستنطبق على كلا الصورتين لكني حقيقة لا أعرف ما المقصود أو ماذا يرمز وجود الرقم "1" قبل الراسيم أو الصورة الأخرى من الرسيم

So, according the very helpful reference provided:
The numbers given in those structures refers to the number of the chiral "C" carbon (the chiral carbon is the carbon of asymmetry"عَدَمُ التَّنَاظِر المِرآتِيّ " chiral ■ adjective Chemistry (of a molecule) not able to be superimposed on its mirror image.) So, when it is number "1" means that the two chains of atoms { let we say "a" and "b" in the reference you provided} selected the carbon number 1 "C1" arbitrarily to be ttached with, and for number "4" they selcet the carbon atom "C4" arbitrarily to be attached with.
وبالتالي فإن ذرة الكربون الكيرالية (أي الكربونة التي تمثلة ذرة عدم التماثل أو التناظر) هي التي تتسبب في التسمية فإما ان تكون رقم "1" وتكتب واحد آر إس أو تكون رقم "4" وتكتب 4 أر إس ، ومن ثم يكون الراسيم واحد آر إس هو الراسيم الناتج عن عدم التناظر (أو ما يسمى بعَدَمُ التَّنَاظِر المِرآتِيّ )عند ذرة الكربون رقم واحد ويكون الراسيم 4 آر إس هو الراسيم الناتج عن عَدَمُ التَّنَاظِر المِرآتِيّ
عند ذرة الكربون رقم 4.

I hope this helps, and i was very happy for this nice technical discussion. I am up to you for any more queries.

too small but I could see C1 C4 etc. So I would personally leave 1RS as is, since it refers to a specific location or 1آر إس but include the English as well. I tried to simplify what Ehab said, so I hope I did not confuse you even more, as it is very

while this link http://www.apvma.gov.au/actives/standard_zeta-cypermethrin.s... shows where the isomerization occurs (1RS, 2Rs etc) refer to the number of the carbon atom at which the variation occurs. I think Ehab referred to that but the writing is

/ a racemic mixture/ a racemic compound, called by UMD راسيمات it is clear in this link http://www.patentstorm.us/patents/5677168.html As for RS1 see this links which says it has 8 isomers http://www.apvma.gov.au/actives/standard_cypermethrin.shtml

refer to two geometric enantiomers which your compound obviously contains (R (-) and S (+). Sorry I was not clear about what I meant above. The compounsd is a 'racemate' (mixture) مزيج أو خليط من.. (we usually say recemic compound) but RS is a racemate.

two enantiomers which could be L- (levo or left) and D- (dextro or right) and they are mirror images of two compounds which have the same molecular formula (e.g. C4H8) but are spatially different and hence called geometric isomers. R and S also

Actually Ehab's answer is right concerning nomenclature (name) and the link he provided is quite good but "racemic' does not apply 'here' as this term refers to optical activity. A racemic compound is not optically active as it has equal amounts of the

I have use the following example for analogy, any corrections would be appreciated:

يتعلق هذا الاختراع بمبيد حشرى جديد . لتحضير هذا المبيد يتم إجراء تفاعل بين ذرة الكربون لمجموعة الفينيل للمبيد الحشرى آلفا ـ سيبرمثرين مع الأسيتون ليعطى مركباً فى صورة شمعية من آلفا ـ سيانو ـ 3 ـ فينوكسى بنزيل ـ3 (2ـ ميثيل ـ 4،4 ـ ثانى ميثيل – 5،5 - ثانى كلوروبيران ) – 2،2 ثانى ميثيل البروبان الحلقى كربوكسيليت .

The components that I am still not sure about is (RS) and (1RS). Ehab's option is the ony solution currently available. For more explanation on this system, you can also check "R,S System" in the following link: http://ccd.chemnetbase.com/intro/index.jsp;jsessionid=50ABC6...

Notes to answerer

Asker: Regarding your suggestion. I have been translating those MSDS Labels for this client for many years without translating the composition of the compound. This time, they have specifically asked for the translation.

Asker: Do you think راسيمي applies to 1RS too, or just RS?

Asker: النوم عذر ولا ريب ولا عذر لمن يواصل الليل بالنهار في العمل. As for the meaning of 1RS, you will find it in the following link, but it needs a specialist like you to understand it: http://ccd.chemnetbase.com/intro/index.jsp;jsessionid=50ABC64E0D6FD2CCE0893BCD57651165
