Claims5
A method for detecting an impurity in a 2-(diethylamino)ethyl 2-acetoxybenzoate hydrochloride product, said impurity being a compound having a formula selected from the group consisting of:
- and said method comprising the steps of:
- (1) providing said 2-(diethylamino)ethyl 2-acetoxybenzoate hydrochloride product;
- (2) obtaining physical/chemical characteristic parameters of said compound A, compound B and/or compound C;
- (3) performing a test on said 2-(diethylamino)ethyl 2-acetoxybenzoate hydrochloride product;
- and
- (4) comparing physical/chemical characteristic parameters resulting from said test with said physical/chemical characteristic parameters of said compound A, compound B and/or compound C, and determining an impurity in said 2-(diethylamino)ethyl 2-acetoxybenzoate hydrochloride product,
- wherein said test in step (3) is preferably selected from the group consisting of a chromatography test, a nuclear magnetic resonance test, an infrared test, a mass spectrometry test, and/or an ultraviolet test.
A method for detecting an impurity in a 2-(diethylamino)ethyl 2-acetoxybenzoate hydrochloride product, said impurity being a compound having a formula selected from the group consisting of:
- and said method comprising the steps of:
- (1) providing said 2-(diethylamino)ethyl 2-acetoxybenzoate hydrochloride product;
- (2) providing said compound A, compound B and/or compound C;
- and
- (3) determining an impurity in said 2-(diethylamino)ethyl 2-acetoxybenzoate hydrochloride product by comparing test results of said 2-(diethylamino)ethyl 2-acetoxybenzoate hydrochloride product in step (1) with test results of said compound A, compound B and/or compound C in step (2),
- wherein said test in step (3) is preferably selected from the group consisting of a chromatography test, a nuclear magnetic resonance test, an infrared test, a mass spectrometry test, and/or an ultraviolet test.
A method for inflammation diminishment comprising:
