CAS No:67-64-1
Mot. Weight:58.08
Mol. Formula:C3H6O
Format:Neat
Storage Temp:20℃±4℃
CERTIFIED：Purity 99.45% (g/g)
CERTIFIED：Expanded Uncertainty (U) 0.71% (g/g)
Uncertainty
The certifled value(s) and uncertaintylies) are determined in accordance with ISO 17034 with an 95% confidence level(k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties of charaterisation. homogeneity and sabilit testing. Stability values are based on real evidence opposed to simulation.
The producer certifies that this reference material meets the specification stated in this certificate until the expiy date,provided it is stored unopened at the recommended temperature herein. Product warranties for this reference matrial are set out in the terms and conditions of purchase.
Method of Characterisation
Purity was determined by elemental analysis
Method of Identification
EA, NMR, RT, IR
Batch Information
Water Content: 0.28% (g/g) by Karl- Fischer-Titration (U(exp) = 0.07% (g/g)).
Intended Use
This RM is intended for use in a laboratory as a calibration and quality control standard or in method development for analytical techniques.
Safety
Proper precautions should be observed while handling. See Safety Data Sheet.
Traceability
The balances used for gravimetric measurements are calibrated with weights traceable to the national standards (DKD). The calibration ofthe balances is verified daily internally and annually by an external accredited calibration service. Chromatographic methods are traceable to the International System of Units (SI).
Homogeneity
Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with
ISO 17034.
Storage
The RM should be stored in the original sealed container at the indicated temperature.
Instructions for use
It is recommended to use 1 mg as theminimum sample size and if lessmaterial is used, to increase thecertified uncertainty by a factor of twofor half sample and four for a quarterof sample. If storage after opening is
necessary, the RM should be tightlyclosed and kept from light andmoisture. If the RM was in a sealedampoule, it should be transferred to avial with minimum head space.
