502221204
N,N-Dimethylformamide 99.8% HPLC Grade Reagent
Cas Number:68-12-2
Formula:C3H7NO
Molar Mass:73.09
EC Number:200-679-5
Physicochemical properties：
Colorless or light yellow liquid with micro-ammonia odour. It is hygroscopic. It is miscible with most organic solvents such as water, ethanol, chloroform and ether, and is slightly soluble in benzene. The pH is 6.70.5 mol/L with aqueous solution. The relative density (d254) is 0.9445.The melting point is -61 ° C. The boiling point is 153 ° C. The refractive index (n25D) is 1.42803. The flash point (open cup)is 67 ° C. The median lethal dose (rat, oral) is 7.6 ml/kg. It can cause fetal damage.
Usage:
Non-aqueous solution titration solvent. The solvent for vinyl and acetylene. Photometric. Gas chromatographic stationary solution (maximum use temperature 50 ° C, solvent methanol), separation and analysis of C2 ~ C5 hydrocarbons, and it can separate positive, isobutylene and cis, anti- 2 - butene. Analysis of pesticide residues. Organic Synthesis. Synthesis of peptides. For the photographic industry.
Packing:
500ml/2.5L/4L
