Chemical Properties
white to light yellow crystal powder
Uses
3,5-Dibromobenzoic acid may be used for the syntheses (+)-menthyl 3,5-dibromobenzoate, di-tert-butyl 4-[2-(tert-butoxycarbonyl)ethyl]-4-(3,5-dibromobenzamido)heptanedioate2, (L)-methyl 2-(3,5-dibromobenzamido)-3-phenylpropanoate.
General Description
3,5-Dibromobenzoic acid is 3,5-dibromo-substituted benzoic acid.
Synthesis
3,5-Dibromobenzoic acid was synthesized from anthranilic acid by bromination, diazotization and additional reactions derived. The bromination reaction is carried out at about 20°C. After the reaction, the crystals are filtered, washed with hot water to remove anthranilic acid and hydrochloric acid, and recrystallized with acetic acid to obtain o-amino-3,5-dibromobenzoic acid; then use sodium nitrite to carry out diazotization in hydrochloric acid at about 0°C, then add the diazonium salt into ethanol containing calcium sulfate at 60-70°C in batches. After the addition is complete, continue stirring for 10 minutes, filter to obtain the crude product, and recrystallize with ethanol to obtain the finished product.
Check Digit Verification of cas no
The CAS Registry Mumber 618-58-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 618-58:
(5*6)+(4*1)+(3*8)+(2*5)+(1*8)=76
76 % 10 = 6
So 618-58-6 is a valid CAS Registry Number.
