Uses
Used in Pharmaceutical Industry:
HEXOPRENALINE SULPHATE is used as a bronchodilator for the treatment of asthma and other respiratory conditions. It works by relaxing the muscles in the airways and increasing the airflow to the lungs, providing relief from breathing difficulties.
HEXOPRENALINE SULPHATE is also used as a tocolytic agent to delay or prevent preterm labor. It helps in relaxing the smooth muscles of the uterus, thus delaying the onset of labor and providing more time for the development of the fetus.
Additionally, HEXOPRENALINE SULPHATE is used as a vasoactive agent in the treatment of certain cardiovascular conditions, such as hypotension or low blood pressure, by constricting blood vessels and increasing blood flow to vital organs.

Manufacturing Process
The N,N'-dibenzyl-N,N'-bis-[2-(3',4'-dihydroxyphenyl)-2-oxoethyl]-
hexamethylene-diamine dichlorohydrate-monohydrate used as the starting
material was prepared as follows: 2 mols of chloroaceto pyrocatechin were
dissolved in 2,000 cc of acetone and heated to boiling with 2 mols of N,N'-
dibenzylhexamethylene-diamine for 12 hours, almost the theoretical quantity
of N,N'-dibenzylhexamethylene-diamine dichlorohydrate being precipitated and
removed by suction after cooling. Excess HCl was added to the filtrate,
approximately 66% of the theoretically possible quantity of crude
dichlorohydrate of the N,N'-dibenzyl-N,N'-bis-[2-(3',4'-dihydroxyphenyl)-2-oxoethyll-hexamethylene-diamine being precipitated. The product was cleaned
by recrystallization from water with the addition of animal charcoal. After
drying the substance contained water of crystallization at ambient
temperature, MP 206° to 209.5°C.
Five grams of N,N'-dibenzyl-N,N'-bis[2-(3',4'-dihydroxyphenyl)-2-oxoethyl]-
hexamethylenediamine dichlorohydrate as a monohydrate were hydrogenated
under considerable agitation by means of 2.0 grams of 10% palladium-carbon,
with hydrogen in a mixture of 270 cc of methanol and 50 cc of water at 45°C
and normal pressure. After about 4 hours the theoretical quantity of hydrogen
(4 mols of hydrogen per 1 mol of substance) was absorbed for the splitting off
of the two benzyl radicals and the reduction of the two carbonyl groups to
carbinol groups, and the hydrogenation came to a stop.
After separation of the catalyst the product was concentrated until dry, the
residue was triturated with acetone, the resulting crystallizate was removed
by suction and washed with acetone. The yield of N,N'-bis-2-(3',4'-
dihydroxyphenyl)-2-hydroxyethyll-hexamethylene-diamine dichlorohydrate was
3.3 grams, i.e., 92% of the theoretical value. A quantity of 2.8 grams having
a melting point of 197.5° to 198°C was obtained by precipitation from a
mixture of methanol-ether.
Free N,N'-bis-[2-(3',4'-dihydroxyphenyl)-2-hydroxyethyl]-hexamethylenediamine can be separated from these salts by the addition of the equivalent
quantity of caustic alkali solution. It has a melting point of 162° to 165°C and
contains half a mol of water of crystallization.
N,N'-bis-[2-(3',4'-dihydroxyphenyl)-2-hydroxyethyl]-hexamethylenediaminesulfate (MP 222° to 228°C) can be obtained by reacting the base with
the equivalent quantity of sulfuric acid in an alcohol solution, followed by
concentration and precipitation from water-alcohol solution.

Check Digit Verification of cas no
The CAS Registry Mumber 3215-70-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,1 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3215-70:
(6*3)+(5*2)+(4*1)+(3*5)+(2*7)+(1*0)=61
61 % 10 = 1
So 3215-70-1 is a valid CAS Registry Number.

Combined doses
-
, (2008/06/13)
The present invention discloses a method and a pharmaceutical dry powder combined dose for the prophylaxis or treatment of a respiratory disorder in a mammalian host by inhalation of a metered dry powder combined dose of finely divided dry medication powders. At least one dry powder medicament is selected from a first group of bronchodilating medicaments and at least one dry powder medicament from a second group of anti-inflammatory medicaments. A metered dry powder medicinal combined dose comprising separately metered deposits of medicinally suitable quantities of each of the selected medicaments is prepared, in which the sum of the metered deposits constitutes the metered quantities of powder of the combined dose and the medicinal combined dose is introduced into an adapted inhaler device for a generally simultaneous delivery of the medicinal combined dose during the course of a single inhalation by a user, such that the delivered medicinal combined dose is composed of a high proportion of mixed de-aggregated fine particles of the selected medicaments, whereby an desired therapeutic or treating effect to the user is achieved.
