is the raw material of drugs for the treatment of skin mold.
This product is basically non-toxic. In the drinking water of rats, 1% sodium octanoate was added for one month without poisoning. But it dissociated acid on the skin and mucous membranes have a stimulating effect, drinking can cause Diarrhea, Vomit and stomach pain. Oral administration is strictly prohibited. Operators should wear rubber gloves.
Packaged in glass bottles or in wooden barrels. According to the general provisions of the storage and transportation of chemicals.
Take 2. 5 g of this product, add 25ml of water to dissolve, and then determine according to law (General rule 0631) , p H value should be 8.0~10. 5.
Take 2. 5 g of this product, add 25ml of water to dissolve, check according to law (General rule 0901 and general rule 0902), the solution should be clear and colorless. In case of color development, it shall not be deeper compared with orange-yellow No. 1 Standard Colorimetric solution (General rules '0901 first method).
take this product, according to the determination of moisture (General rule 0832 The first method) determination, containing moisture not more than 3 .0%.
take 3.0g of this product, add 15ml of glacial acetic acid and 15ml of ethanol to dissolve, take 25ml as the test solution. Inspection according to law (General Principles 0821, law I), containing heavy metals shall not exceed 5 parts per million.
take this product about 0. 12G, add 5 m l of water to dissolve, add 1ml of dilute sulfuric acid, shake well, add 1 0 m l of ethyl acetate, shake extraction, let stand to separate layers, take ethyl acetate layer, after drying with anhydrous sodium sulfate, take the supernatant as the test solution; Take im l with precision, put it in a 100ml measuring flask, dilute it with ethyl acetate to the scale, and shake it well, 5 m l was accurately measured, placed in a 50ml measuring flask, diluted to the scale with ethyl acetate, and shaken to serve as a control solution. Another caprylic acid control product, about 10m g, was dissolved by adding ethyl acetate (10m) as a control solution. According to the test of gas chromatography (General rule 0521), the capillary column with 2-nitroterephthalic acid modified polyethylene glycol 20 m as stationary liquid was used as the chromatographic column (30m x 0. 25mm idx0. 2 5 p m ); The initial temperature is 100°C, which is maintained for 1 minute, and then the temperature is raised to 220°C at a rate of 5°C per minute, which is maintained for 20 minutes; The inlet temperature is 250°C; the temperature of the detector was 25V; The test solution and the control solution were measured by 1 ^ 1, respectively, and the human gas chromatograph was injected and the chromatogram was recorded. The signal-to-noise ratio of the control solution shall not be less than 5; According to the area normalization method, the single impurity in the chromatogram of the test solution shall not pass 0 .3%, total impurities should not be over 0 .5%, the area of any main peak in the chromatogram of the test solution is less than 0.5 times the peak is negligible.
take this product about 0.15g, precision weighing, add 50ml of glacial acetic acid to dissolve, according to the potentiometric titration method (General 0701), with perchloric acid titration solution (0. lm o l/L) titration, and the results of the titration were corrected with a blank test. Each lm l perchloric acid titration solution (0. lm o l/L) corresponds to 16.62 mg of C8 H15Na02.

Use | Used in the pharmaceutical industry In the pharmaceutical industry, biological agents (human albumin) contain sodium caprylate as an inactive ingredient. In terms of biology, higher acid salts are generally used for the special selection of strains. The reason why salts are used is that salts have greater solubility than higher acids themselves. And the PH value is better adjusted. For example, when breeding bacteria that can degrade caprylic acid, sodium caprylic acid needs to be added to the culture medium. In the field of chemistry: sodium caprylate can be used to decarboxylate to produce high-purity n-heptane sodium caprylate is used as a protein stabilizer in biological preparations |
