138377-66-9 Usage
Uses
Used in Textile Industry:
HC Yellow No. 15 is used as a coloring agent for various materials, primarily in the textile industry, to provide vibrant yellow hues and ensure high color fastness properties. Its application is crucial for achieving long-lasting coloration in fabrics and yarns, enhancing their visual appeal and durability.
In the textile industry, the use of HC Yellow No. 15 serves multiple purposes:
1. As a primary dye for coloring fabrics and yarns in their natural state, providing a consistent and uniform coloration.
2. As a secondary dye for blending with other dyes to create a wide range of shades and hues, expanding the color palette available for textile designers and manufacturers.
3. As a means to improve the colorfastness of textiles, ensuring that the dyed materials maintain their color vibrancy even under exposure to sunlight, washing, and other environmental factors.
While the provided materials do not mention other specific industries for the use of HC Yellow No. 15, it is worth noting that azo dyes, in general, have applications beyond the textile industry. They can be used in various fields such as:
Paper and pulp industry: For coloring paper products and improving their aesthetic appeal.
Food industry: As colorants in certain food products, although strict regulations apply due to potential health concerns.
Cosmetics industry: As pigments in makeup and personal care products to provide color and enhance visual appeal.
However, it is essential to consider the safety and environmental impact of using azo dyes like HC Yellow No. 15 in different applications, as some may release harmful aromatic amines when broken down, posing potential health and ecological risks.
Check Digit Verification of cas no
The CAS Registry Mumber 138377-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,7 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138377-66:
(8*1)+(7*3)+(6*8)+(5*3)+(4*7)+(3*7)+(2*6)+(1*6)=159
159 % 10 = 9
So 138377-66-9 is a valid CAS Registry Number.

Novel JAK1-selective benzimidazole inhibitors with enhanced membrane permeability

The previously identified Janus kinase 1 (JAK1)-selective inhibitor, 1-(2-aminoethyl)-2-(piperidin-4-yl)-1H-benzo[d]imidazole-5-carboxamide (2), suffered from low cell permeability, which resulted in poor pharmacokinetic properties. In this study, by introducing less polar hydrogen bond donors at N1(a hydroxyalkyl or a methylaminoalkyl group) and C2 (a cyclohexanol group) positions, a series of novel benzimidazole derivatives were prepared, which exhibited selective JAK1 inhibitory activity (IC50against JAK1?=?0.08–0.15?μM; JAK1-selectivity?=?26–40 fold vs JAK2, 12–23 fold vs JAK3, and 38–54 fold vs Tyk2) along with significantly increased lipophilicity (3.3–15.8 times) as well as membrane permeability (6.3–12 times).

The novel hair dye compositions containing a compound of the formula: STR1 where R1, R2, R3 and R4 which may be identical or different, are hydrogen, alkyl, hydroxyalkyl, polyhydroxyalkyl, alkoxyalkyl, hydroxyalkoxyalkyl aminoalkyl and dialkylaminoalkyl, each alkyl group and each alkoxy group having from about 1 to about 6 carbons and R5 is hydrogen or alkyl containing from about 1 to about 6 carbon atoms are disclosed. More specifically, the present invention concerns the inclusion of such compounds of formula I in hair dye compositions as direct dyes, and especially the novel compound 4-(2-hydroxyethylamino)-3-nitrobenzamide. The compounds, some of which are novel, provide a yellow dye base for the hair dyeing compositions.
