Chemical Structure

Chromium(III) standard for ICP CAS 13548-38-4 chemical structure

Description

As a certified reference material (CRM), Chromium(III) standard for ICP 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.

Chromium(III) standard for ICP (CAS 13548-38-4) is a high-purity analytical reference standard with the molecular formula NO3Cr and a molecular weight of 114.00 g/mol.

Structurally, Chromium(III) standard for ICP (NO3Cr) contains an inorganic composition. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 114.00 g/mol, it falls into the low-molecular-weight range. 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.
