4222-96-2 Usage
Description
Levonorgestrel Impurity N, also known as 13-Ethylgon-5(10)en-3,17-dione, is an impurity derived from the synthesis of Levonorgestrel (N689510), which is an oral contraceptive. It is a chemical byproduct that is produced during the manufacturing process of the contraceptive and is typically monitored and controlled to ensure the safety and efficacy of the final product.
Uses
Used in Pharmaceutical Industry:
Levonorgestrel Impurity N is used as a reference material for quality control and analytical testing in the pharmaceutical industry. It is essential for ensuring the purity and potency of the final Levonorgestrel product, which is an oral contraceptive.
Levonorgestrel Impurity N is used as a research compound for studying the synthesis, properties, and potential applications of Levonorgestrel and its related compounds. This can help in the development of new contraceptive formulations or other therapeutic applications involving Levonorgestrel.
Used in Regulatory Compliance:
Levonorgestrel Impurity N is used as a reference substance in regulatory compliance testing. It helps in the assessment of the manufacturing process and the quality of the final product, ensuring that the impurity levels are within the acceptable limits as per the regulatory guidelines.
Check Digit Verification of cas no
The CAS Registry Mumber 4222-96-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4222-96:
(6*4)+(5*2)+(4*2)+(3*2)+(2*9)+(1*6)=72
72 % 10 = 2
So 4222-96-2 is a valid CAS Registry Number.

SILICA GEL PROMOTED SELECTIVE HYDROLYSIS OF 3-METHOXY-2,5(10)-DIENE STEROIDS
Lui, Li-Gong,Zhang, Tong,Li, Zhen-Su

Hydrolysis of 3-methoxy-2,5(10)-diene steroids (1a-c) via oxalic acid in the presence of silica gel was developed as a fast selective synthesis method toward corresponding 5(10)-en-3-ones (2a-c) in good yield (51-94percent).This also provided a new method for selective ketalisation of 17-keto over 3-keto (2c).
