Mechanism of toxicity
The compound readily eliminates a chloride ion by intramolecular nucleophilic substitution to form a cyclic sulfonium ion. This very reactive intermediate tends to permanently alkylate the guanine nucleotide in DNA strands, which prevents cellular division and generally leads directly to programmed cell death or, if cell death is not immediate, the damaged DNA may lead to the development of cancer Sulfur mustard is not very soluble in water but is very soluble in fat, contributing to its rapid absorption into the skin.Attachment 113985
In the wider sense, compounds with the structural element BCH2CH2X, where X is any leaving group and B is a Lewis base are known as mustards. Such compounds can form cyclic "onium" ions (sulfonium, ammoniums, etc.) that are goodalkylating agents. Examples are bis(2-chloroethyl)ether, the (2-haloethyl)amines (nitrogen mustards), and sulfur sesquimustard, which has two α-chloroethyl thioether groups (ClH2C-CH2-S-) connected by an ethylene (-CH2CH2-) group. These compounds have a similar ability to alkylate DNA, but their physical properties, e.g. melting point, vary.
Mary would probably have an orgasm were he to read this.

Pretty sure Mary doesn't like orgasms. She just likes looking at pretty girls.
also, I preferred mbm's c&p about jamie oliver being a spacker.
Re: I think I know what's up with Idol.
Rather I think Idol was calling out to me due to my absence in this thread, at least that's how I was approaching the excerpt. At first I thought I was reading about an aggressive chemotherapy technique until I saw that it alkylates guanine indiscriminately, then thinking, "what are they trying to do, kill people?". I finally reached the later portion of it and realized it was describing the mechanism by which mustard gas is harmful. Did any of you, any at all, bother to read it? I won't say that it's poorly written, but it could be much improved.
I carry two lethal weapons in my house, my left elbow and my right knee. I've only handled an unloaded handgun once, after my Texan neighbor's friend accidentally fired a round into his floor (instead of through the drywall leading to my bedroom).

Didn't have to, I realised that it was a descriptor of the mechanism by which its harmful by the title. It even says toxicity.
I'm surprised it took you til the latter portion of it to glean this information.
You know, what with being a chemistry student and all :]
Re: I think I know what's up with Idol.
I can see I'm in hostile territory. I label you all terrorists, and will shoot on site. In fact, I fired a warning shot at my monitor. It grazed my son's head, but luckily he's already retarded, so no real damage done.
BTW, Where's skiz when I need him? :fear:

My eyes are drawn to figures, I don't have to be elitist every time.

Skizo is out hunting for deer to shoot and then decapitate.
I've never quite got over seeing that pic.
Not saying it made me go all Idol but just the sheer pointlessness of the head in a bucket.

That's the beauty of being one of the cognoscenti. You don't have to be, it's an elephant and it's in the room yet your associates don't let it diminish your relationship with them. Not if you do it correctly.
You'll learn this, one day, when you pass your exams and get a job and get promoted to auspiciousness.

Too many Texans.Too many guns.Too few things that make our eyes light up with child-like wonder at their grace and beauty..

The mundanity of your presentation made me want to commit suicide.
