Chemical Structure

hydroiodic acid CAS 10034-85-2 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

hydroiodic acid (CAS 10034-85-2), molecular formula HI and molecular weight 127.91 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, hydroiodic acid (HI) contains iodine substitution. 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 127.91 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), hydroiodic acid 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.
