Description

7774-29-0 R03O05RB0P Mercuric iodide Mercuric iodide, red Mercury diiodide Mercury iodide (HgI2) Mercury(II) iodide EINECS 231-873-8 HSDB 1211 Hydrargyrum bijodatum [German] Mercury biniodide alpha-Mercury(II) iodide Red mercuric iodide Hydrargyrum diodatum Mercurius bijodatus Hydrargyrum bijodatum UNII-R03O05RB0P (CAS 7774-29-0), molecular formula HgI2 and molecular weight 454.40 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 7774-29-0 R03O05RB0P Mercuric iodide Mercuric iodide, red Mercury diiodide Mercury iodide (HgI2) Mercury(II) iodide EINECS 231-873-8 HSDB 1211 Hydrargyrum bijodatum [German] Mercury biniodide alpha-Mercury(II) iodide Red mercuric iodide Hydrargyrum diodatum Mercurius bijodatus Hydrargyrum bijodatum UNII-R03O05RB0P (HgI2) 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 454.40 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 7774-29-0 R03O05RB0P Mercuric iodide Mercuric iodide, red Mercury diiodide Mercury iodide (HgI2) Mercury(II) iodide EINECS 231-873-8 HSDB 1211 Hydrargyrum bijodatum [German] Mercury biniodide alpha-Mercury(II) iodide Red mercuric iodide Hydrargyrum diodatum Mercurius bijodatus Hydrargyrum bijodatum UNII-R03O05RB0P 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.
