3 Requirements

3.1 Composition and appearance. This product should be in line with the original drug diniconazole standard with suitable additives and fillers processed into for loose uniform composition Powder, there should be no lumps. 3.2 diniconazole WP should meet the requirements of Table 1. Table 1 diniconazole WP Control Project Index Item Index Diniconazole mass fraction /% 12.5 ± 0.7 Diniconazole suspension rate /% ≥ 70 pH range of 7.0 to 11.0 Moisture /% ≤ 3.0 Wetting time/s ≤ 90 Fineness (through 45μm test sieve) /% ≥ 95 Thermal storage stability of a qualified a thermal storage stability test, test at least once every 3 months. Test Method 4 4.1 Sampling Carried out according to GB/T 1605 "solid preparation sampling" method. Determining sample package by random sampling method, the final sample size should not be Less than 300g. 4.2 Identification Test HPLC --- The identification test with diniconazole determination simultaneously. Under the same chromatographic operating conditions, the sample One solution peak retention time compared with standard sample solution diniconazole chromatographic retention time, the relative difference should be less than 1.5%. When using the above method for identification of effective ingredients have questions, other effective methods can be used for identification. 4.3 Determination of the mass fraction of diniconazole 4.3.1 Method summary Sample dissolved in mobile phase, methanol + water as the mobile phase, use as filler to C18 stainless steel column and UV detector (250nm), Other than the standard method of sample diniconazole reverse phase HPLC separation and determination. 4.3.2 Reagents and solutions Methanol. HPLC grade; Water. The new secondary steam distilled water; Diniconazole standards. a known mass fraction ≥99.0%. 4.3.3 Instruments High performance liquid chromatography. a variable wavelength UV detector; Chromatographic data processor or chromatography workstation; Column. 250mm × 4.6mm (. I.d) stainless steel column, built ZORBAXSB-C18,5μm filler (or other equivalent effect Column); Filter. filter pore size of about 0.45μm; Micro injector. 50μL; Ultrasonic cleaner. 4.3.4 HPLC operating conditions Mobile phase. ψ (methanol. water) = 85.15, by membrane filtration, and degassing; The mobile phase flow rate. 1.0mL/min; Column temperature. room temperature (temperature change should not exceed 2 ℃); Detection wavelength. 250nm; Injection volume. 5μL; Retention time. Diniconazole about 5.6min, diniconazole isomers about 4.5min.

According to the standard 4.3 Determination diniconazole quality, calculate the suspension rate. 4.4.2 Calculation Sample 2 was suspended rate (%) according to equation (2). 100 (2) Where. 4.4.3 allowable difference The difference between two parallel determination results shall not be greater than 5% of the arithmetic mean as a measurement result. 4.5 Determination of Moisture According to GB/T 1600 "on azeotropic distillation method". According to GB/T 1601 carried out. 4.7 Determination of wetting time According to GB/T 5451 carried out. 4.8 Determination of fineness According to GB/T 16150 in the "wet sieve method". 4.9 Thermal storage stability test 19136 by method GB/T "powder formulation" will be completed testing diniconazole mass fraction and suspension rates within 24h after the heat storage set. Diniconazole content should not be less than the reservoir before the mass fraction of 95%, was still suspended shall meet the standards. 4.10 Product inspection and acceptance Shall comply with GB/T 1604's.
