Glycinamide Hydrochloride CAS 1668-10-6 (H-Gly-NH2·HCl) Assay 99.0~101.0% Factory High Quality

Melting point: Capillary determination method. Should be 200.0~205.0℃
The sample was ground into powder of about 0.1g and dried in a blast oven at 105℃ for half an hour, then loaded into a capillary tube and packed. When the oil temperature in the melting point instrument rises to 190℃, put the capillary into it and control the heating rate at 3℃ per minute. Observe the initial melting point of the contents of the capillary and continue heating until all the contents in the capillary melt to the final melting point.
Content: Titration by AgNO3
Weigh the sample 0.2000g, dissolve it in distilled water and dilute it to 100ml, add 3-5 drops of potassium chromate indicator, and titrate with 0.1000M standard silver nitrate to the end point.
Calculation: Content %=V×M÷G×0.1105×100
V- Volume consumed by standard silver nitrate titration in ml
M- standard silver nitrate concentration mol/L
G- Weigh the sample g
Moisture measurement:
K-F method: Add 10ml anhydrous methanol into the precision moisture meter, titrate K-F reagent with water equivalent greater than 3mg/ml to the end point, quickly sample 1.0000g, put into the above anhydrous methanol, titrate with K-F reagent to the end point; Record the titration volume ml.
Calculation: Moisture =V×N÷G×100÷1000
N--The water equivalent of the K-F reagent   mg/ml
V---The volume consumed by the K-F reagent titration ml
G-- Weigh the sample g
