4175-37-5 Usage
General Description
4-octyl-N-phenylaniline (OPA) is a chemical compound that consists of an octyl group and a phenyl group attached to an aniline molecule. It is used as a surfactant and emulsifier in many industrial applications, including the production of paints, coatings, and adhesives. OPA is also used as an intermediate in the synthesis of various organic compounds, and as a corrosion inhibitor for metals. It is known for its ability to reduce the surface tension of liquids and improve their dispersibility, making it a valuable ingredient in many formulations. However, OPA should be handled with care due to its potential health and environmental hazards, and proper safety measures should be taken when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 4175-37-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,7 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4175-37:
(6*4)+(5*1)+(4*7)+(3*5)+(2*3)+(1*7)=85
85 % 10 = 5
So 4175-37-5 is a valid CAS Registry Number.

, (2008/06/13)
New composition comprises a functional fluid in contact with ferrous metal and a corrosion inhibiting amount of at least one compound of formula (I) STR1 or a derivative thereof in which R1, R2 and R3 are, independently, hydrogen, a C1 -C15 straight or branched chain alkyl residue, a C5 -C12 cycloalkyl residue, a C6 -C15 aryl residue or C7 -C12 alkaryl residue, and R4 and R5 are, independently, hydrogen, 2-hydroxyethyl or 2-hydroxypropyl with the provisos that (a) R4 and R5 are not simultaneously hydrogen, (b) when R4 and R5 are each --CH2 --CH2 --OH, R1 and R2 are not simultaneously hydrogen and R3 is not a pentyl residue and (c) that polyalkylene and phenol or polycarboxylic ester co-additives are absent; as well as salts thereof. Some of the compounds of formula I are new.
