115-41-3 Usage

Chemical Properties

greenish yellow powder

Uses

Different sources of media describe the Uses of 115-41-3 differently. You can refer to the following data:
1. A complexometric indicator.
2. Pyrocatechol Violet is a complexometric indicator dye. This phthalein dye chelates metals to form blue to blue-violet complexs. It is also a pH indicator with a transition interval from 0 - 8 (red to violet). It is known to be unstable when alkaline. The stability is improved at a neutral pH. When the pH is between 2-7 the color may be yellow. Dyes and metabolites.

Purification Methods

It is recrystallised from glacial acetic acid. It is very hygroscopic and is an indicator standard for metal complex titrations. [Mustafin et al. Zh Anal Khim 22 1808 1967, Beilstein 19/3 V 703.]

Check Digit Verification of cas no

The CAS Registry Mumber 115-41-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 115-41:
(5*1)+(4*1)+(3*5)+(2*4)+(1*1)=33
33 % 10 = 3
So 115-41-3 is a valid CAS Registry Number.
