Chemical Structure

Terbium(III) nitrate hexahydrate CAS 13451-19-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Terbium(III) nitrate hexahydrate.

Terbium(III) nitrate hexahydrate (CAS 13451-19-9) is a high-purity analytical reference standard with the molecular formula TbNO3H2O and a molecular weight of 238.95 g/mol.

Owing to an inorganic composition, Terbium(III) nitrate hexahydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Terbium(III) nitrate hexahydrate 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.
