Pyridine is a basic heterocyclic organic compound with the chemical formula C5H5N. It is structurally related to benzene, with one methine group (=CH-) replaced by a nitrogen atom. The pyridine ring occurs in many important compounds, including azines and the vitamins niacin and pyridoxal.
Pyridine was discovered in 1849 by the Scottish chemist Thomas Anderson as one of the constituents of bone oil. Two years later, Anderson isolated pure pyridine through fractional distillation of the oil. It is a colorless, highly flammable, weakly alkaline, water-soluble liquid with a distinctive, unpleasant fish-like odor.
Pyridine is used as a precursor to agrochemicals and pharmaceuticals and is also an important solvent and reagent. Pyridine is added to ethanol to make it unsuitable for drinking (see denatured alcohol). It is used in the in vitro synthesis of DNA, in the synthesis of sulfapyridine (a drug against bacterial and viral infections), antihistaminic drugs tripelennamine and mepyramine, as well as water repellents, bactericides, and herbicides. Some chemical compounds, although not synthesized from pyridine, contain its ring structure. They include B vitamins niacin and pyridoxal, the anti-tuberculosis drug isoniazid, nicotine and other nitrogen-containing plant products. Historically, pyridine was produced from coal tar and as a by-product of the coal gasification. However, increased demand for pyridine resulted in the development of more economical methods of synthesis from acetaldehyde and ammonia, and more than 20,000 tonnes per year are manufactured worldwide.
[Intro:]
No no no no
No no no
What they told me
[Chorus:]
People use to tell me this could neva happen now I just smile and grin
This is what they told me
I told it would happen when I was much older nobody believe me then
Now they hear me on the radio
And they can't hate no mo
See me on the t.v. shows
Even the videos
I told it would happen
And this is what they told me
[Verse 1:]
I knew life would get better if I just stick to my dream
When or when but it gets hard some times
So much temptation we livin life on the line
I don't even think people know what I been through
Contracts and contacts can stress you
But strong faith
But keep it movin on
Keep it pressen on
Until the lord takes me home
[Chorus:]
People use to tell me this could neva happen now I just smile and grin
This is what they told me
I told it would happen when I was much older nobody believe me then
Now they hear me on the radio
And they can't hate no mo
See me on the t.v. shows
Even the videos
I told it would happen
And this is what they told me
[Verse 2:]
This force is such a struggle cause I have been around
Those who don't love me seem like they jealous of
The talent that I got from the heavens above
Why don't you say what you say when say what said to me
If you don't like what I doin
If you don't like what I'm doin then dirty just let me be
Look I walk strickly by faith and dirty not by sight
Cause every thang that look good ain't always right
I learn from experiance to me it's so serious
Even though I'm curious
No more hard times
The world is bout to be mine
Nobody taken my shine
Forget bout what you told me
[Chorus: x4]
People use to tell me this could neva happen now I just smile and grin
This is what they told me
I told it would happen when I was much older nobody believe me then
Now they hear me on the radio
And they can't hate no mo
See me on the t.v. shows
Even the videos
I told it would happen
