Chemical Directory Can Come in Two Flavors
Have you ever needed to find the chemical composition of an object or material? Have you ever wanted to know what a certain compound was made from? If so, then a chemical directory would be very helpful. The two different types of directories are a qualitative and quantitative chemical directory. Qualitative directories list all the ingredients in alphabetical order according to their common names and will show corresponding diagrams for those ingredients. Quantitative directories take things one step further by listing chemicals in descending order by weight, meaning that the heavier compounds will always be listed first followed by lighter ones. Therefore, a chemical directory that only lists chemicals by weight (like this one) would be a quantitative chemical directory.
Aqualab's universal chemical catalog is available in both quantitative and qualitative formats, as well as a family of specialized solutions for specific needs. Whether it is for reading an article about dental health or for finding the specific chemistry behind your favorite perfume, Aqualab has something just for you.
The link to this directory can found after the jump.

Now some of you might be wondering "Why are there two different types of directories? Is it just for cosmetics or is there a reason behind this?" Well actually the answer to this is because most substances can be found in both forms, such as the case with Perfume. The compound below is methylpyrrole, and it's the component that gives perfume its strong odor.
[[ARTICLE START]]
Methylpyrrole (IUPAC name) or 1-methylpyrrole is a chemical compound that smells like rotting fish. It has an extremely offensive, pungent odor and also tastes sour but not bitter to the tongue. It's a human carcinogen (lung cancer) and a mutagen (causes genetic damage). It also causes skin irritation. Its boiling point is 133 °C and it has a melting point of 24.2 °C. It's sparingly soluble in cold water but miscible with hot water. Also, it will dissolve in chloroform, ethanol, dioxane, diethyl ether, dimethyl sulfoxide (DMSO), acetone, acetonitrile and N-methylpyrrolidone. It's a monoisotopic molecule. Methylpyrrole has one chiral center, which can be racemic or enantiomeric. It has a melting point of 18-19 °C and boiling point of 90 °C. Its solubility in water is 1 mg/l (0.1 μM) at 25 °C and its molecular weight is 88.32 g/mol. It's a consentrated product with iodine number 111, sulfur number 62 and oxygen number 35.

With this in mind, you can see how the qualitative and quantitative directory were created. These are two different types of chemical directories that have different uses. I hope this article helps you out and answers your questions about chemical directories. Thanks for reading and don't forget to join the discussion. August 17, 2013 at 8:12 PM Flag Quote & Reply

For it is God who gives you power to get wealth, so that in everything you may have confidence. He will grant that to you which is your heart's desire, and he will not deny you anything [of such desire]. (Philippians 4:19, NKJV)
I AM GOD AND THERE IS NO OTHER, EXCEPT ME. I HAVE CREATED ALL THINGS AND I AM IN CONTROL OF EVERYTHING IN THE UNIVERSE. Satan mocked Jesus when He said , "Which one of us has ever seen God? What we've heard about Him [is] like [the descriptions in] a fable or historical legend. No one has ever seen God. If we're going to talk about who is God, we should begin with the one who created all things—so that man would have a model and standard of what God is." (John 4:24-25, NLT)

God gave Adam life in our Earth at the beginning of the creation.
They were created in God's image.
Man is the only creature who can talk and think for himself. This made him like God. It also made him very important in God's plan to rule the universe.
The first thing that Adam did was stand up and take his place on Earth.
God gave Adam a job to do—to name every living thing on Earth. He wanted Adam to be able to tell each other animal apart, so they would know each other better. The names of those things that were important to the people living then are still used today, such as dog, cow, horse, and sheep. So this way everyone would know their own animals by these names.
Conclusion
The goal of all this is to really just have a better understanding of everything and to have something to base your life on, whether it be science or religion. It does bring a lot of questions into the picture, but science can answer the questions about chemicals, the human body and Earth, but religion can answer the questions about heaven and hell. They work together to create this amazing world we live in today. I hope that you will be able to use all this information wisely in your life. You'll be surprised at how many thing you were misinformed of before. Either way, thank you for reading and I hope that God has blessed you with peace.
