Package: Bottle, Aluminium foil bag, 25kg/Cardboard Drum, or according to customer's requirement.
Storage Condition: Keep the container tightly closed and store in a cool, dry (2~8℃) and well-ventilated warehouse away from incompatible substances. Protect from light and moisture.
Shipping: Deliver to worldwide by air, by FedEx / DHL Express. Provide fast and reliable delivery.
5.3.1 Appearance: It should be light yellow to yellow powder. Visually, lay sufficient quantity of test product (without weighing) in a clean crystal dish on a white background (such as white paper) under natural light.
5.3.2 Identification: 1H-NMR has the same structure as the standard. 10~15mg of the sample was weighed into the nuclear magnetic tube, and 0.5mL of deuterium DMSO was added to fully dissolve the sample, and then tested with a nuclear magnetic resonance instrument of more than 400MHz.
5.3.3 Loss on drying : Weigh the sample about 1.0g and dry it for 3h in a drying oven at 85℃. The specific operation for weight loss calculation shall be performed according to the provisions of SOP-AP-QC-002-01 for Determination of Drying Weight Loss.
5.3.4.1 Chromatographic conditions:
Test reagents: 1) acetonitrile for chromatography 2) purified water 3) phosphoric acid
Column: WondaCract ODS-2 4.6*250mm*5um (8520-39993)
Mobile phase: A: Accurately measure 1.0ml phosphoric acid and 1000ml water, filter ultrasonic degassing.
B: Acetonitrile.
Gradient procedure: the following table
Time mobile phase A (%) Mobile phase B (%)
3 90 10

5.3.4.2 Solution preparation:
5.3.4.3 Diluent: acetonitrile
5.3.4.4 Blank solution: diluent shall be used as blank solution.
5.3.4.5 Test product solution: Weigh the test product about 12.5mg in a 25ml volumetric bottle and dissolve it with diluent to the scale.
5.3.4.6 Operation procedure: After the baseline of the instrument is stable, one to two injections of blank solution are advanced, and then the solution of the test product is analyzed. The chromatogram is saved and analyzed, blank peak is deducted, and the main peak purity and single impurity results on the chromatogram of the test product are recorded by area normalization method. After the analysis, the chromatogram was printed.
