1138-67-6 Usage
General Description
1,2-Benzenediol, 4-phenoxy- (9CI) is a chemical compound with a molecular formula C12H10O3. It is also known as 4-phenoxy resorcinol and is commonly used in the production of hair dyes, permanent wave products, and other hair care products. It is often added to these products as a coloring agent or as a substance to enhance the overall performance of the product. 1,2-Benzenediol, 4-phenoxy- (9CI) has also been studied for its potential use in the treatment of pigmentation disorders and as an ingredient in sunscreen products due to its ability to protect the skin from ultraviolet radiation. However, there are concerns about the potential for skin irritation and allergic reactions in some individuals.
Check Digit Verification of cas no
The CAS Registry Mumber 1138-67-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1138-67:
(6*1)+(5*1)+(4*3)+(3*8)+(2*6)+(1*7)=66
66 % 10 = 6
So 1138-67-6 is a valid CAS Registry Number.

Biotransformation of diphenyl ether by the yeast Trichosporon beigelii SBUG 752
Schauer, Frieder,Henning, Kirsten,Pscheidl, Helmut,Wittich, Rolf M.,Fortnagel, Peter,et al.
, p. 173 - 180 (2007/10/03)
Trichosporon beigelii SBUG 752 was able to transform diphenyl ether. By TLC, HPLC, GC, GC-MS, NMR- and UV-spectroscopy, several oxidation products were identified. The primary attack was initiated by a monooxygenation step, resulting in the formation of 4-hydroxydiphenyl ether, 2-hydroxydiphenyl ether and 3-hydroxydiphenyl ether (48:47:5). Further oxidation led to 3,4-dihydroxydiphenyl ether. As a characteristic product resulting from the cleavage of an aromatic ring, the lactone of 2-hydroxy-4-phenoxymuconic acid was identified. The possible mechanism of ring cleavage to yield this metabolite is discussed.
