39240-08-9 Usage
General Description
3-(N,N-Diethyl)aminobenzanilide, also known as Benzocaine, is a white, odorless powder that is commonly used as a local anesthetic. It is chemically classified as an ester and is often found in over-the-counter medications such as numbing creams, sprays, and lozenges to relieve pain and itching from minor skin irritations or insect bites. Benzocaine works by inhibiting the transmission of nerve signals, thereby numbing the area where it is applied. It is also used as a topical anesthetic during medical procedures and in some dental treatments. However, excessive use of benzocaine can lead to potentially serious side effects, including allergic reactions and methemoglobinemia, a condition that reduces the amount of oxygen carried in the blood. Therefore, it is important to use Benzocaine as directed by a healthcare professional.
Check Digit Verification of cas no
The CAS Registry Mumber 39240-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,4 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 39240-08:
(7*3)+(6*9)+(5*2)+(4*4)+(3*0)+(2*0)+(1*8)=109
109 % 10 = 9
So 39240-08-9 is a valid CAS Registry Number.

Synthesis and Spectral Characterization of Blue Dyes of the Benzene Series
Thiel, W.,Mayer, R.,Jauer, E.-A.,Modrow, H.,Dost, H.
, p. 497 - 514 (2007/10/02)
53 Donor-acceptor substituted azo dyes of the benzene series were prepared by diazonium-coupling reactions (1a-s) or halogen-cyanide exchange (->2a-x, 3a-j).Described are the preparation of the amines 4a-m and the coupling compounds 5a-t and the procedure of diazotizing and coupling.The colouristic and spectroscopic data show that compounds of the general formula 1 are excellent brilliant blue azo dyes usefull for dyeing polyester material.
