The invention relates to a phosphoryl carboxylic acid propofol ester derivative which has the general formula (I). The method comprises the following steps: propofol reacts with 2-halogenated carboxylic acid and a derivative thereof by alkali to obtain corresponding ester and then the product reacts with phosphoric acid or thiophosphoric acid and the derivative thereof by dissolvent to obtain a water-soluble product or the propofol reacts with a 2-halogenated carboxylic acid phosphate ester derivative by the alkali to obtain the corresponding ester and then the ester is catalyzed, hydrogenated and salified to obtain the water-soluble product (I). The preparation method has mild reaction condition, high yield, simple operation and industrialized prospect, and a prepared oral preparation has the characteristics of high bioavailability, rapid absorption, high stability, and the like; and auxiliary materials with safety defects, such as a surface active agent, and the like can not be added into the prepared injection, thereby improving the stability of the preparation, reducing or removing injection pain, increasing the compliance of patients, overcoming the defects of propofol emulsion and having the advantage of obvious effect. The invention has the structural general formula (I).

The invention discloses a method for monitoring traced propofol narcotic rapidly and sensitively. In the method, an ion mobility spectrometry technology is taken as a basic detection technology, and an anion mode is adopted to establish a method for monitoring traced propofol narcotic. The method comprises the following steps: feeding a gas sample containing propofol into an ion mobility spectrometry tester for analysis to obtain a detecting signal, and then carrying out qualitation and quantitation. According to the invention, the measurement of a narcotic sample can be detected in real time, and the limit of detection of the propofol narcotic can reach 0.5ppb. The detecting method is simple, convenient, rapid and efficient and is good in reliability.

Irritation upon injection of a formulation containing propofol is reduced or substantially eliminated by administering a stable, sterile, and antimicrobial aqueous dispersion comprising a water-insoluble microdroplet matrix of mean diameter from about 50 nm to about 1000 nm consisting essentially of about 1% to about 15% of propofol, up to about 7% of a propofol-soluble diluent, and about 0.8% to about 4% of a surface stabilizing amphiphilic aent. The aqueous phase includes a pharmaceutically acceptable water-soluble polyhydroxy tonicity modifier. The propofol-containing dispersion is devoid of additional bactericidal or bacteriostatic preservative agents.

Methods of monitoring Propofol through a supply chain are disclosed herein. Consequently, the methods perform authentication of propofol as it is transported through the supply chain to the end user whereby propofol manufacturers and distributors can achieve data and product integrity and ultimately minimize cost.

The present invention discloses an accurate quantitative analysis method for an ion mobility spectrum rapid detection sample. According to the method, based on the migration time obtained through qualitative analysis of an ion mobility spectrum, the thermal analysis process of the whole sample to be detected is completely recorded, and the recorded curve is defined as the tracking trend line of the thermal analysis of the sample; the samples with different concentrations are prepared by adopting the ion mobility spectrum technology as the base detection technology, and the tracking trend of the sample is subjected to data analysis; and by adopting the propofol in blood as an example, a standard curve equation y=671.48+934.42.x of the ion mobility spectrum detection is established between the plasma concentration of 1-20 ppm, wherein the correlation coefficient r is 0.9928. According to the present invention, the method is simple, rapid and efficient, and can be widely used for the quantitative analysis of the ion mobility spectrum rapid detection sample.
