Purification Methods
The hydrochlorde can be recrystallised from small volumes of EtOH. Alternatively it is dissolved in EtOH, filtered, Et2O is added; filter the crystalline salt off under N2 and dry it in a vacuum desiccator over H2SO4. The salt is deliquescent and should be stored in a tightly stoppered container. Its solubility in H2O is 10% at room temperature and it is soluble in Me2CO. The free base reacts strongly alkaline in H2O. It has max 224nm ( 4000) in H2O. The picrate has m 252o (sintering at ~245o).

Check Digit Verification of cas no
The CAS Registry Mumber 124-42-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 124-42:
(5*1)+(4*2)+(3*4)+(2*4)+(1*2)=35
35 % 10 = 5
So 124-42-5 is a valid CAS Registry Number.

The invention provides a preparation method of cefathiamidine hydrochloride. In particular, by adopting a reverse dropwise adding manner, the intermediate product vinylidene chloride is added dropwise to the ammonia methanol to generate stable cefathiamidine, and the reverse dripping mode not only effectively inhibits the decomposition of the aramidine, but also the yield of cefathiamidine hydrochloride can reach 95% or above. The method is safe to operate. The method is high in yield and low in energy consumption, and is very suitable for large-scale application.
