Test material

Constituent 1
Reference substance name:
Reaction product of acid red 143 (free acid) or the respective sodium salt (e.g Lansyn red F-5B) (UVCB) with Tetrabutylammonium bromide (CAS nr.: 1643-19-2) resulting in a mixture of AR143-(TBN)2 (Main component), AR143-(TBN), AR143-(TBN)3, AR143-(TBN) without alkyl tail, AR143-(TBN)2 without alkyl tail. Chemical name main component AR143-(TBN)2: di-(tetra-n-butylammonium) salt of 1-benzoyl-4-[4'-(1'',1''-dimethylpropyl)-phenoxy]-6-phenylamino-2,7-dioxo-2,7-dihydro-3H-naphtho(1,2,3-de)quinolin, disulfonic acid
EC Number:
944-248-6
Molecular formula:
Combinations of mono (C40H31N2O7S1) bi (C40H30N2O10S2) and trivalent (C40H29N2O13S3) AR143 with TBN (C16H36N+)
IUPAC Name:
Reaction product of acid red 143 (free acid) or the respective sodium salt (e.g Lansyn red F-5B) (UVCB) with Tetrabutylammonium bromide (CAS nr.: 1643-19-2) resulting in a mixture of AR143-(TBN)2 (Main component), AR143-(TBN), AR143-(TBN)3, AR143-(TBN) without alkyl tail, AR143-(TBN)2 without alkyl tail. Chemical name main component AR143-(TBN)2: di-(tetra-n-butylammonium) salt of 1-benzoyl-4-[4'-(1'',1''-dimethylpropyl)-phenoxy]-6-phenylamino-2,7-dioxo-2,7-dihydro-3H-naphtho(1,2,3-de)quinolin, disulfonic acid

Results and discussion

Melting / freezing point
Melting / freezing pt.:
97 °C
Atm. press.:
1 atm
Remarks on result:
other: Tg-onset

Any other information on results incl. tables

In the 1st heat run an evaporation effect is seen between 0-150°C, probably due to rest solvent. No melting effects at temperatures between 200-250°C are visible. The solvent has disappeared in the 2nd heat run and a clear Tg of 97°C can be determined.

In the 1st heat run an evaporation effect is seen between 0-150°C, probably due to rest solvent. No melting effects at temperatures between 200-250°C are visible. The solvent has disappeared in the 2nd heat run and a clear Tg of 97°C can be determined.
