Description
Econazole nitrate is the nitrate salt form of Econazole. It belongs to imidazole-class antifungal medication sold in various places around the world including US, Canada, Western Europe, and Asia. It is usually manufactured into cream form for sale. Econazole nitrate is mainly used for the treatment of skin infections including athlete's foot, tinea, pityriasis versicolor, ringworm, and jock itch caused by fungi such as Trichophyton rubrum, Trichophyton tonsurans and Microsporum audouini. As an imidazole-class drug, Econazole nitrate takes effects through inhibiting the biosynthesis of ergosterol, a key component of fungal cell membrane, thus disrupting the normal permeability of fungal membrane. This causes leakage of essential cellular contents of fungi, further killing them.

Uses
Different sources of media describe the Uses of 24169-02-6 differently. You can refer to the following data:
1. Antifungal;Ergosterol synthesis inhibition
2. Azole antifungal
3. Econazole nitrate is an antifungal agent of the imidazole type used in topical and vaginal preparations to prevent growth of dermatophytes, yeast, and mold.
Manufacturing Process
A suspension of 10.3 parts of α-(2,4-dichlorophenyl)-imidazole-1-ethanol and
2.1 parts of sodium hydride in 50 parts of dry tetrahydrofuran is stirred andrefluxed for 2 hours. After this reaction-time, the evolution of hydrogen is
ceased. Then there are added successively 60 parts dimethylformamide and 8
parts of p-chlorobenzylchloride and stirring and refluxing is continued for
another two hours. The tetrahydrofuran is removed at atmospheric pressure.
The dimethylformamide solution is poured onto water. The product, 1-[2,4-
dichloro-β-(p-chlorobenzyloxy)phenethyl]imidazole, is extracted with benzene.
The extract is washed with water, dried, filtered and evaporated in vacuo.
From the residual oily free base, the nitrate salt is prepared in the usual
manner in 2-propanol by treatment with concentrated nitric acid, yielding,
after recrystallization of the crude solid salt from a mixture of 2-propanol,
methanol and diisopropylether, 1-[2,4-dichloro-β-(pchlorobenzyloxy)phenethyl]imidazole nitrate; MP 162°C.
Brand name
Spectazole (Johnson & Johnson).
Therapeutic Function
Antifungal
General Description
White crystalline powder.
Air & Water Reactions
Insoluble in water.
Fire Hazard
Flash point data for Econazole nitrate are not available; however, Econazole nitrate is probably combustible.
Biochem/physiol Actions
Econazole interacts with 14-α demethylase, a cytochrome P-450 enzyme necessary to convert lanosterol to ergosterol. Inhibition of ergosterol results in increased cellular permeability causing leakage of cellular contents. Econazole may also inhibit endogenous respiration, interact with membrane phospholipids, inhibit the transformation of yeasts to mycelial forms, inhibit purine uptake, and impair triglyceride and phospholipid biosynthesis.
Check Digit Verification of cas no
The CAS Registry Mumber 24169-02-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,1,6 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 24169-02:
(7*2)+(6*4)+(5*1)+(4*6)+(3*9)+(2*0)+(1*2)=96
96 % 10 = 6
So 24169-02-6 is a valid CAS Registry Number.
