Uses
Different sources of media describe the Uses of 37091-65-9 differently. You can refer to the following data:
1. Antibacterial;Bacterial transpeptidase inhibitor
2. Azlocillin sodium is a semisynthetic penicillin and is a potent 1-lactam antibiotic. It is often used against Pseudomonas aeruginosa and has been used to develop novel antibiotic quantitation techniques.
Manufacturing Process
3.8 parts by weight of D-(-)-α-[(imidazolidin-2-on-1-yl)carbonylamino]phenylacetic
acid were dissolved in 65 parts by volume of dichloromethane. 2.7
parts by weight of 1-methyl-2-chloro-δ1-pyrrolinium chloride were added, and
after cooling to -10°C 2.0 parts by volume of triethylamine were added
gradually. This reaction mixture was then stirred for one hour at -5°C
(mixture A). 4.0 parts by weight of 6-aminopenicillanic acid in 80 parts by
volume of dichloromethane were treated with 4.4 parts by volume of
triethylamine and 4.0 parts by weight of anhydrous sodium sulfate and then
stirred for two hours at room temperature. After filtration, the solution was
cooled to -20°C and combined with the mixture A. The reaction mixture was
left to reach 0°C of its own accord, and was then stirred for a further hour at
0°C. The solvent was removed in a rotary evaporator, the residue was
dissolved in water, and the solution was covered with a layer of ethyl acetate and acidified with dilute hydrochloric acid at 0° to 5°C, while stirring, until pH
1.5 was reached. The organic phase was then separated off, washed with
water, dried over magnesium sulfate while cooling, and filtered, and after
dilution with an equal amount of ether the sodium salt of the penicillin was
precipitated from the filtrate by adding a solution of sodium 2-ethylcaproate
dissolved in ether containing methanol. Yield: 1.3 parts by weight.

Check Digit Verification of cas no
The CAS Registry Mumber 37091-65-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,0,9 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 37091-65:
(7*3)+(6*7)+(5*0)+(4*9)+(3*1)+(2*6)+(1*5)=119
119 % 10 = 9
So 37091-65-9 is a valid CAS Registry Number.

The invention discloses a preparation method of azlocillin and a preparation method of azlocillin sodium freeze-dried powder for injection. The preparation method of the azlocillin comprises the steps that 25-35 parts of an ampicillin thihydrate, 55-65 parts of acetone, 240-260 parts of water and 4-6 parts of dioxane and tetrahydrofuran are added into a reaction container by weight under the room temperature condition and stirred to be uniform, wherein the weight part ratio of dioxane to tetrahydrofuran is (6-8):1; 6-12 parts by weight of triethylamine is dropwise added into the reaction container when the temperature of the materials in the reaction container is lowered to 10 DEG C-15 DEG C, and stirring is performed to enable the solution in the reaction container to be completely clear; 9.10-12.74 parts by weight of 1-chloroformyl-2-imidazolidinone is slowly added into the reaction container when the temperature of the materials is lowered to 5 DEG C-10 DEG C, the temperature is kept at 15 DEG C-20 DEG C, and reacting under stirring is performed for 2.5-3.5 h; the pH is regulated to be 3-4 by adding hydrochloric acid, crystallization of the azlocillin is performed under the 3 DEG C-5 DEG C condition, and a precipitate is separated out; filtering is performed, and a precipitate is taken, leached by acetone and then subjected to vacuum drying. The preparation method of the azocillin is high in yield, the prepared azocillin is high in purity, and no solvent is retained.
