Embodiment Construction

[0023] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

[0024] Apparatus needed for the present invention

[0025] An ultraviolet spectrophotometer (TU-1901) was purchased from Beijing Puxi General Instrument Co., Ltd.

[0026] Samples required for the present invention

[0027] The standard sample of 2,3-dibenzylsuccinic acid was provided by the R&D Department of Shangyu Zhongxian Biotechnology Co., Ltd., and 6 batches of 2,3-dibenzylsuccinic acid samples to be tested (No. 20140601, 20140602, 20140603, 20140604 , 20140605, 20140606) were provided by the cyclic acid production workshop of Zhejiang Sixian Pharmaceutical Co., Ltd., and the rest of the reagents were of analytical grade.

[0028] The method for rapid detection of 2,3-dibenzylsuccinic acid content of the present invention comprises the following steps:

[0029] (1) Steps of scanning the UV abso...

Abstract

The invention relates to a method for rapidly detecting the content of 2,3-dibenzyl succinic acid. The method comprises the following steps: (1) confirming the maximum absorption wavelength by virtue of scanning of a 2,3-dibenzyl succinic acid ultraviolet absorption spectrum; (2) preparing a 2,3-dibenzyl succinic acid standard sample solution; (3) acquiring a 2,3-dibenzyl succinic acid standard curveinear regression equation; (4) preparing a to-be-detected 2,3-dibenzyl succinic acid sample; (5) detecting 2,3-dibenzyl succinic acid by using ultraviolet light; and (6) calculating the concentration of 2,3-dibenzyl succinic acid. By adopting the method, the content of 2,3-dibenzyl succinic acid can be detected, so that the yield and quality of a later reaction product can be controlled. The method is simple in operation, low in detection cost, accurate in detection result and applicable to rapid detection on a midbody in the production process.

Description

technical field [0001] The invention relates to a method for measuring substance content, in particular to a new method for quickly and efficiently detecting the content of 2,3-dibenzylsuccinic acid. Background technique [0002] 2,3-Dibenzylsuccinic acid is an intermediate in the synthesis of vitamin H. Vitamin H, also known as biotin and coenzyme R, is an indispensable substance for the normal metabolism of fat and protein. Water-soluble vitamins necessary for body function. Has been widely used in medicine, cosmetics, animal feed additives and other aspects. Due to the long synthetic route of vitamin H, in order to produce high-quality final product vitamin H, it is necessary to control the content of intermediates in the synthetic route. [0003] 2,3-Dibenzylsuccinic acid is an intermediate produced by a synthetic route using benzylamine and dibromosuccinic acid as raw materials. It reacts with triphosgene to form a cyclic acid. Due to the special property of 2,3-dibe...
