Poly(vinyl alcohol) CRS CAS 9002-89-5 chemical structure

Description

As a certified reference material (CRM), Poly(vinyl alcohol) CRS meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Poly(vinyl alcohol) CRS (CAS 9002-89-5), molecular formula C2H4O and molecular weight 44.05 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C2H4O, Poly(vinyl alcohol) CRS contains a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 44.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
