74695-40-2 Usage
General Description
BUTTPARK 145\18-49 is a mixture of chemicals commonly used as a stabilizer and antioxidant in plastics and rubber products. It is composed of various compounds, including phenolic and amine antioxidants, phosphites, and other stabilizers. This combination of chemicals helps to prevent degradation of the polymer material, such as discoloration, cracking, and loss of mechanical properties, caused by exposure to heat, light, and oxygen. BUTTPARK 145\18-49 is often used in the production of high-performance plastic and rubber products, such as automotive parts, electrical cables, and industrial equipment, to improve their durability and longevity. It is important to handle and use this chemical mixture with proper safety precautions, as it may pose health and environmental risks if not managed carefully.
Check Digit Verification of cas no
The CAS Registry Mumber 74695-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,9 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74695-40:
(7*7)+(6*4)+(5*6)+(4*9)+(3*5)+(2*4)+(1*0)=162
162 % 10 = 2
So 74695-40-2 is a valid CAS Registry Number.

Thienopyridines. Part 3. The Preparation of Some 6-Substituted 7-Hydroxythienopyridin-5(4H)-ones and Some Reactions of 7-Hydroxythienopyridin-5(4H)-one.

Reaction of 3-amino-2-alkoxycarbonylthiophens with compounds such as diethyl malonate or ethyl cyanoacetate produced amides, which were cyclised to 6-substituted-7-hydroxythienopyridin-5(4H)-ones by treatment with sodium hydride in dimethyl-formamide.Hydrolysis of the 6-ethoxycarbonyl derivative yielded 7-hydroxythienopyridin-5(4H)-one; some aspects of the chemistry of this substance, and of chloro-compounds derived from it, have been studied.
