Approval and usages of Citalopram Hydrobromide
Citalopram is an antidepressant drug of the selective serotonin reuptake inhibitor (SSRI) class. It has U.S. Food and Drug Administration (FDA) approval to treat major depression, which it received in 1998 and is prescribed off-label for other conditions. In UK, Germany, Portugal, Poland, and most European countries it is licenced for depressive episodes and panic disorder with or without agoraphobia. In Spain it is also used for obsessive-compulsive disorder.
Citalopram hydrobromide(CAS NO:59729-32-7) is a medicine which is used in depression and panic disorder. It is used to treat a variety of mental health problems. It is thought that Citalopram hydrobromide increases the activity and levels of certain chemicals in the brain. This can improve symptoms such as depression and anxiety. It is used for treating most depression cases, except for bipolar depression, as it may actually aggravate the symptoms, or cause sudden unprecedented and rapid mood swings from depressive moods to manic moods.
Side effects of Citalopram Hydrobromide
Common side effects of Citalopram Hydrobromide include drowsiness, insomnia, nausea, weight changes, vivid dreaming, frequent urination, decreased sex drive, anorgasmia, dry mouth, increased sweating, trembling, diarrhea, excessive yawning, and fatigue.
However, just as there are two sides of every coin, there are certain citalopram hydrobromide serious side effects that people taking this medication must be aware of.
One of the side effects is the development of an allergic reaction to citalopram hydrobromide. There are certain people who have an idiosyncratic allergy to this drug. In such cases, normally after a single dose itself, the person starts developing an allergic reaction to it, like rashes, itching, fever, irritability, excessive sweating etc.
Another most dangerous side effect is the possibility of citalopram hydrobromide causing suicidal thinking and suicidal tendencies if taken on a long term basis. This may especially occur if the person develops another parallel depressive disorder. This is one of the reasons why this drug is not given to anyone below 18 years of age.

Malic acid is a kind of colorless, crystalline compounds, the molecule formula is COOHCH2CHOHCOOH, that occurs naturally in a wide variety of unripe fruit, including apples, cherries, and tomatoes, and is used as a flavoring and in the aging of wine.
In winemaking, when certain bacteria convert Malic acid(CAS NO:636-61-3) to lactic acid (which is much less strong and sour), a process called "malolactic fermentation" occurs. This reduces the wine's tartness, adds complexity to the flavor and sometimes contributes a slight sparkle.Malic acid is used as an acidulant as well as a flavoring agent in the processing of some foods.
What is differnece in D(+)-Malic acid and L-malic acid?
There are two different structures of malic acid(CAS NO:636-61-3), L-Malic acid and D(+)-Malic acid. The only difference between the two is that they rotate the light shining on them in two different directions. L-Malic acid is produced naturally in fruits. 90% of the acid in apples is malic acid. When malic acid is produced synthetically, a mixture of the two isomers is obtained which is called DL-malic acid (because it contains both D(+)- and L-malic acid). When you eat DL-malic acid, your body digests it in just the same way as it does for L-malic acid. It is part of the Krebs cycle.
Is malic acid a natural product?
There are two forms of malic acid; the L-Malic acid is found naturally in most fruits and many vegetables in varying amounts. Of the total acid content in apples, 90-98% is L-malic acid. Malic acid can also be produced synthetically from maleic anhydride. It is impossible to choose whether natural L-malic acid or the unnatural D(+)-Malic acid is formed during synthesis so a mixture of the two is formed, often called DL-malic acid. It is most likely that if malic acid is used as an additive, it is the synthetic DL-malic acid. The body metabolises the two forms in exactly the same way.
How is malic acid purified?
Malic acid can be produced in a pure form by crystallising it out of water when it has been made synthetically from maleic anhydride, which in turn is made simply from butane gas. This reaction process leads to a mixture of the two malic acid isomers. To purify the natural form of L-malic acid, it is necessary to remove it from apples or other fruits where malic acid is present in a high concentration. This can be done by fractionated distillation. Green apples are best for this since 90% of the acid present in them is malic acid.

Melting Point:155-158 C
Flash Point:127 C
Appearance:yellowish-beige powder
EINECS:211-833-6

Stability:Stable at room temperature in closed containers under normal storage and handling conditions.
Storage Temperature: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
2,6-Dihydroxyacetophenone(CAS NO: 699-83-2), three-necked round-bottomed flask is fitted with a reflux condenser, a dropping funnel, and a glass tube, extending to the bottom of the flask, connected to a cylinder of nitrogen.
In the flask are placed 148 g. (0.68 mole) of 4-methyl-7-hydroxy-8-acetylcoumarin and 500 ml. of distilled water. A rapid stream of nitrogen is bubbled through the water suspension until all the air in the apparatus is displaced, and then a slow stream of the gas is kept passing through the solution.
A solution of 129 g. (3.23 moles) of sodium hydroxide in 580 ml. of water is added through the dropping funnel, and the mixture is heated on a steam bath for 5 hours. The solution is then cooled and acidified by the addition of about 1 l. of dilute (1:3) hydrochloric acid. The stream of nitrogen gas is continued throughout the period of heating and while the solution is cooling. It may be stopped after the solution is acid.
The crude 2,6-Dihydroxyacetophenone which separates on acidification is collected on a filter, washed three times with 50-ml. portions of cold water, and air-dried. A yield of 90-95 g. (87-92% based on the 4-methyl-7-hydroxy-8-acetylcoumarin) of light-yellow solid is obtained.
The purification is accomplished by dissolving the crude product in 1 l. of 95% ethanol, adding 20 g. of Norit, and heating the mixture on a steam cone for 15 minutes with occasional shaking. After this time, 800 ml. of warm water is added, and the solution is heated 5 more minutes and filtered through a hot funnel.
The greenish filtrate is chilled in an ice-salt bath, and the first crop (about 65 g.) of lemon-yellow needles of 2,6-Dihydroxyacetophenone is removed by filtration. The filtrate is then concentrated under reduced pressure to a volume of 800 ml., again chilled, and the second crop of product (about 15 g.) collected on a filter. The total yield of purified 2,6-Dihydroxyacetophenone, melting at 154-155 C, is 75-85 g. (a recovery of 83–89%) .
