Application:
This product is white or white crystalline or crystalline powder; Odorless or almost odorless. This product is slightly soluble in methanol, slightly soluble in chloroform or ethanol, and insoluble in water or ether. The melting point of this product (Appendix Ⅵ C) should be 178 ~ 184 ℃, and it will decompose simultaneously during melting.
Assay:
Take about 0.25g of the product, weigh it accurately, add glacial acetic acid-acetic anhydride (1:1)35ml, dissolve it, titrate with perchloric acid titration solution (0.1mol/L) by potentiometric titration method (Appendix â…¦ A), and calibrate the titration result with blank test. Each 1ml of perchloric acid titration solution (0.1mol/L) is equivalent to 47.92mg of C18H14Cl4N2O.HNO3.
