Embodiment 1

[0080] Use the chiral chromatographic column of ovomucin as the stationary phase; With 0.08% trifluoroacetic acid aqueous solution (regulating the pH value with triethylamine to be 3.0) the volume ratio of water phase and methanol is 99: 1 as mobile phase; 0.8ml per minute; detection wavelength is 230nm.

[0081] Under this condition, detect need testing solution, contrast solution and the detection spectrum that contrast substance solution obtains are similar to Figure 1-1A , Figure 1-1B with 1-1C . After replacing the organic phase with ethanol, isopropanol, acetonitrile or any combination of them, as long as other conditions remain unchanged, the detection results are similar.

Embodiment 2

[0083] Use the chiral chromatographic column of ovomucin as the stationary phase; the volume ratio of 0.10% trifluoroacetic acid aqueous solution (adjusting the pH value to 3.5 with triethylamine) and methanol is 85:15 as the mobile phase; the flow rate is 0.8 per minute ml; detection wavelength is 200nm.

[0084] Under this condition, detect need testing solution, contrast solution and the detection spectrum that contrast substance solution obtains are similar to Figure 1-2A , Figure 1-2B with 1-2C . After replacing the organic phase with ethanol, isopropanol, acetonitrile or any combination of them, as long as other conditions remain unchanged, the detection results are similar.

Embodiment 3

[0086] Use the chiral chromatographic column of ovomucin as the stationary phase; the volume ratio of 0.15% trifluoroacetic acid aqueous solution (adjusting the pH value to 4.0 with triethylamine) and methanol is 80:20 as the mobile phase; the flow rate is 0.8 per minute ml; detection wavelength is 227nm.

[0087] Under this condition, detect need testing solution, contrast solution and the detection spectrum that contrast substance solution obtains are similar to Figure 1-2A , Figure 1-2B with 1-2C . After replacing the organic phase with ethanol, isopropanol, acetonitrile or any combination of them, as long as other conditions remain unchanged, the detection results are similar.

Abstract

The invention provides a separation method for tirofiban hydrochloride isomer, and a metering method for D-configuration tirofiban hydrochloride. By adjusting high performance liquid chromatography conditions, the separation flexibility of the tirofiban hydrochloride isomer is improved by 3 to 10 times, and the separation degree is improved to be more than 2.0, so that the accuracy of the D-configuration tirofiban hydrochloride is improved obviously.

Description

Technical field: [0001] The present invention relates to a kind of separation method of isomer and the quantitative method of D configuration isomer, specifically the present invention relates to a kind of separation method of tirofiban hydrochloride isomer and D configuration tirofiban hydrochloride quantitative method. Background technique: [0002] The chemical name of tirofiban is "N-(n-butylsulfonyl)-O-[4-(4-piperidinyl)butyl]-L-tyrosine". Tirofiban has the following chemical structure [0003] [0004] After tirofiban is salted, especially tirofiban hydrochloride, it has been widely used to treat patients with unstable angina or non-Q wave myocardial infarction, prevent cardiac ischemic events, and is also suitable for coronary ischemic syndrome coronary angioplasty or intracoronary atherectomy to prevent cardiac ischemic complications associated with sudden occlusion of the treated coronary artery. [0005] It can be seen from the above structural formula of tir...
