Uses
Betanidine is a betacyanin and an aglycone of the beet dye betanin.
Manufacturing Process
A mixture of 2-bromobenzylamine (12.5 g) and S-methylthiouronium sulfate
(10 g) in water (20 ml) was heated for 1.5 hours on a steam bath in a hood,
during which methylmercaptan escaped (as evidenced by a foul odour). The
reaction mixture was then cooled and diluted with ethanol (100 ml). A
colourless solid of 2-bromobenzylguanidine sulfate was separeted, and washed
with ethanol. This solid melted at 230-232°C; it was recrystallized from water
and then melted at 247-248°C. By action of a basic agent the salt obtained
may be converted into free base.
Therapeutic Function
Antihypertensive
Check Digit Verification of cas no
The CAS Registry Mumber 55-73-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 55-73:
(4*5)+(3*5)+(2*7)+(1*3)=52
52 % 10 = 2
So 55-73-2 is a valid CAS Registry Number.

CURABLE COMPOSITION
-
, (2010/12/30)
The present invention has its object to provide a curable composition which comprises a guanidine compound as a non-organotin type catalyst, is less discolored, has good surface curability, depth curability, strength rise and adhesiveness, and can retain the curability even after storage; the above object can be achieved by a curable composition which comprises: (A) an organic polymer containing a silyl group capable of crosslinking under siloxane bond formation, the silyl group being a group represented by the general formula (1): -SiX 3 (1) (wherein X represents a hydroxyl group or a hydrolyzable group and the three X groups may be mutually the same or different), (B) a guanidine compound (B-1) as a silanol condensation catalyst, and (C) a plasticizer, wherein the content of the component (B-1) is not lower than 0.1 part by weight but lower than 8 parts by weight per 100 parts by weight of the component (A), and a non-phthalate ester plasticizer accounts for 80 to 100% by weight of the (C) component plasticizer.
