Uses

Used in Hormonal Contraceptives:
2,4-Pentadienoic acid, 3-methyl-5-[(1S,2S)-2-methyl-2-(5,6,7,8-tetrahydro-3,5,5,8,8-pentamethyl-2-naphthalenyl)cyclopropyl]is used as a progestin in combination with estrogen for hormonal contraceptives. It prevents ovulation and alters the cervical mucus and uterine lining, making it difficult for sperm to reach the uterus and for a fertilized egg to implant.
Used in Management of Endometriosis:
In the Gynecology industry, 2,4-Pentadienoic acid, 3-methyl-5-[(1S,2S)-2-methyl-2-(5,6,7,8-tetrahydro-3,5,5,8,8-pentamethyl-2-naphthalenyl)cyclopropyl]is used as a therapeutic agent for the management of endometriosis. It helps to reduce the symptoms and progression of this condition by affecting the hormonal balance.
Used in Treatment of Abnormal Uterine Bleeding:
2,4-Pentadienoic acid, 3-methyl-5-[(1S,2S)-2-methyl-2-(5,6,7,8-tetrahydro-3,5,5,8,8-pentamethyl-2-naphthalenyl)cyclopropyl]is used as a treatment for abnormal uterine bleeding. It helps to regulate the menstrual cycle and reduce excessive bleeding by modulating the hormonal levels.
Used in Hormone Replacement Therapy:
In the field of Menopause Management, 2,4-Pentadienoic acid, 3-methyl-5-[(1S,2S)-2-methyl-2-(5,6,7,8-tetrahydro-3,5,5,8,8-pentamethyl-2-naphthalenyl)cyclopropyl]is used as a component of hormone replacement therapy. It helps to alleviate symptoms of menopause by providing the necessary hormonal support and maintaining hormonal balance.
Available in Various Oral Dosage Forms:
2,4-Pentadienoic acid, 3-methyl-5-[(1S,2S)-2-methyl-2-(5,6,7,8-tetrahydro-3,5,5,8,8-pentamethyl-2-naphthalenyl)cyclopropyl]is available in different oral dosage forms, such as tablets and extended-release tablets, for convenient administration and optimal therapeutic effects.

Check Digit Verification of cas no

The CAS Registry Mumber 260262-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,2,6 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 260262-39:
(8*2)+(7*6)+(6*0)+(5*2)+(4*6)+(3*2)+(2*3)+(1*9)=113
113 % 10 = 3
So 260262-39-3 is a valid CAS Registry Number.
