The occurrence of Zinc oxalate dihydrate is closely related to a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Zinc oxalate dihydrate (CAS 55906-21-3) is a high-purity analytical reference standard with the molecular formula C2H4O6Zn and a molecular weight of 189.46 g/mol.
Owing to a carboxylic acid group, an ether linkage, Zinc oxalate dihydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 189.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Zinc oxalate dihydrate 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.
