Article Code:DRE-C11850000

Lot Number: G766082 
Article Name: Cyfluthrin

Expiry Date: 03.08.2024 
Formula: C22H18CI2FNO3

Storage Temperature: 20℃ ± 4℃ 
Mol. Weight: 434.29
CAS No.: 68359-37-5

Storage and handling: The RM should be stored in the original sealed bottle at the temperature given aboveAfter use the bottle should be tightly closed ang protected from moisture.
Purity: 98.95%(g/g) 
Expanded UncertaintyU= 0.30%(g/g)

The uncertainty of this standard is calculated in accordance with the ISO Guide 34 and EURACHEM/ITAC Guide-Quantifying Uncertainty in Analytical Measurement Second Edition. The expanded uncertainty is U(exp)=u(RM)xk,where k is the coveragefactor at the 95%confidence level(k=2).Uncertainty u(RM) is based on the combination of the uncertainties associated with each individual operation involved in the analysis of theproduct:u(RM)=Vu(char)²+u(bb)²+u(Its)²+u(sts)² ; u(char) is the uncertainty of characterisation;u(bb)uncertainty of homogeneity test;u(lts)uncertainty of stability test long-term;u(sts)uncertainty of stability test short-term.u(lts)and u(sts)are not included in the calculation as the stability statement is based on real evidence opposed to simulation
Minimum sample: 1 mg is recommended as the minimal sample amount.If less material is used,it is recommended to increase the certified uncertainty by a factor of two for half sample and a factor of four for a quarter of sample.
Intended use: Use this RM as calibrant for chromatography or any other analytical technique.
