915-67-3 Usage


Amaranth (FD & C Red No. 2) consists essentially of a trisodium 2-hydroxy-l-(4-sulfonato-1-naphthy lazo)naphthalene 3,6-disulfonate and subsidiary coloring matters together with sodium chloride and/or sodium sulfate as the principal uncolored components. Amaranth may be converted to the corresponding aluminum lake.

Chemical Properties



Dyeing wool and silk bright bluish-red from an acid bath. Food colorant. As indicator. In color photography.


An azo dye derived from naphthionic and R acids.

World Health Organization (WHO)

Approval of amaranth as a permitted colouring agent in foods and pharmaceutical products was withdrawn by the United States FDA in 1976, on the basis of positive findings in carcinogenicity tests which were later disputed on technical grounds and which have not been confirmed in subsequent tests. It has since been withdrawn by some other national regulatory authorities because of uncertainty regarding its safety, but elsewhere it remains widely used.

General Description

Dark red to dark purple powder. Almost no odor. Tastes salty. pH (1% solution in water) approximately 10.8. Used to dye wool and silk bright bluish-red from an acid bath.

Air & Water Reactions

Can be explosive as an airborne dust at certain concentrations. Moderately soluble in water.

Reactivity Profile

Check Digit Verification of cas no

The CAS Registry Mumber 915-67-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,1 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 915-67:
83 % 10 = 3
So 915-67-3 is a valid CAS Registry Number.
