Before the nineteenth century, chemists generally believed that
compounds obtained from living organisms were endowed with a vital force
that distinguished them from inorganic compounds. According to the concept of vitalism (vital force theory), organic matter was endowed with a "vital force".During the first half of the nineteenth century, some of the first
systematic studies of organic compounds were reported. Around 1816 Michel Chevreul started a study of soaps made from various fats and alkalis.
He separated the different acids that, in combination with the alkali,
produced the soap. Since these were all individual compounds, he
demonstrated that it was possible to make a chemical change in various
fats (which traditionally come from organic sources), producing new
compounds, without "vital force". In 1828 Friedrich Wöhler produced the organic chemical urea (carbamide), a constituent of urine, from inorganic starting materials (the salts potassium cyanate and ammonium sulfate), in what is now called the Wöhler synthesis.
Although Wöhler himself was cautious about claiming he had disproved
vitalism, this was the first time a substance thought to be organic was
synthesized in the laboratory without biological (organic) starting
materials. The event is now generally accepted as indeed disproving the
doctrine of vitalism.
In 1856 William Henry Perkin, while trying to manufacture quinine accidentally produced the organic dye now known as Perkin's mauve. His discovery, made widely known through its financial success, greatly increased interest in organic chemistry.
A crucial breakthrough for organic chemistry was the concept of chemical structure, developed independently in 1858 by both Friedrich August Kekulé and Archibald Scott Couper. Both researchers suggested that tetravalent
carbon atoms could link to each other to form a carbon lattice, and
that the detailed patterns of atomic bonding could be discerned by
skillful interpretations of appropriate chemical reaction.
Since organic compounds often exist as mixtures, a variety of techniques have also been developed to assess purity, especially important being chromatography techniques such as HPLC and gas chromatography. Traditional methods of separation include distillation, crystallization, and solvent extraction.
Organic compounds were traditionally characterized by a variety of
chemical tests, called "wet methods", but such tests have been largely
displaced by spectroscopic or other computer-intensive methods of
analysis. Listed in approximate order of utility, the chief analytical methods are:
Nuclear magnetic resonance (NMR) spectroscopy is the most commonly used technique, often permitting complete assignment of atom connectivity and even stereochemistry using correlation spectroscopy.
The principal constituent atoms of organic chemistry – hydrogen and
carbon – exist naturally with NMR-responsive isotopes, respectively 1H and 13C.
Elemental analysis: A destructive method used to determine the elemental composition of a molecule. See also mass spectrometry, below.
Mass spectrometry indicates the molecular weight of a compound and, from the fragmentation patterns,
its structure. High resolution mass spectrometry can usually identify
the exact formula of a compound and is used in lieu of elemental
analysis. In former times, mass spectrometry was restricted to neutral
molecules exhibiting some volatility, but advanced ionization techniques
allow one to obtain the "mass spec" of virtually any organic compound.
Crystallography can be useful for determining molecular geometry
when a single crystal of the material is available and the crystal is
representative of the sample. Highly automated software allows a
structure to be determined within hours of obtaining a suitable crystal.
Traditional spectroscopic methods such as infrared spectroscopy, optical rotation, UV/VIS spectroscopy
provide relatively nonspecific structural information but remain in use
for specific classes of compounds. Traditionally refractive index and
density were also important for substance identification.

Answer: ACASC charges a service fee of 50$ for using its online application portal. Applying through ACASC into Chinese universities attracts a service fee of $50.
Answer: Yes. ACASC gives the applicants, the chance to directly apply to their desired universities through our online application portal. We have synchronized our system to create a simple platform that connects universities and colleges in China to international students all around the world.
Answer: To track the application status, please log in your ACASC personal account. Whenever there’s an update, you will be informed on your application status through ACASC system within a day as soon as we receive university’s notification. You will simultaneously receive ACASC auto-email about the application status. To directly inquire about your application status, feel free to send us an email to admission@acasc.cn and our team will keep you updated.
Answer: When an application is pending a decision it means that your school has received it and no admissions decision has been made yet. The admissions office may have reviewed your application package or may not have.
The main cause of a pending application is usually incomplete application documents. As a result you will be requested by the school’s admission office to re-check and modify all submitted application documents or perhaps even add extra documents and then re-submit them.
To avoid further delays, carefully read the university’s comments, modify your application form on ACASC, and re-upload the required application documents. You can contact ACASC on admission@acasc.cn for any help with regards to your pending application
Processing time varies for different applications. For example to process a degree program application requires more time than a Chinese language application. Confirmation for Chinese language application by the admission office usually takes 2 to 4 weeks. However, time for degree programs application differs. For example fall semester application processing is after March, and it takes a period of 1 to 2 months. This also depends on your qualification and the number of applicants.
