Description
The occurrence of 3 inverted exclamation marka,6 inverted exclamation marka-bis(Acetyloxy)-4,5,6, 7-tetrachloro-2 inverted exclamation marka,4 inverted exclamation marka,5 inverted exclamation marka,7 inverted exclamation marka-spiro[isobenzofuran-1(3H), 9 inverted exclamation marka-[9H]xanthen]-3-one 61738-01-0 Rose Bengal diacetate Spiro[isobenzofuran-1(3H), 9 inverted exclamation marka-[9H]xanthen]-3-one is closely related to a flavonoid core, a hydroxyl group, an ether linkage, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3 inverted exclamation marka,6 inverted exclamation marka-bis(Acetyloxy)-4,5,6, 7-tetrachloro-2 inverted exclamation marka,4 inverted exclamation marka,5 inverted exclamation marka,7 inverted exclamation marka-spiro[isobenzofuran-1(3H), 9 inverted exclamation marka-[9H]xanthen]-3-one 61738-01-0 Rose Bengal diacetate Spiro[isobenzofuran-1(3H), 9 inverted exclamation marka-[9H]xanthen]-3-one (CAS 61738-01-0), molecular formula C24H8Cl4I4O7 and molecular weight 1057.75 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, chlorine/iodine substitution, 3 inverted exclamation marka,6 inverted exclamation marka-bis(Acetyloxy)-4,5,6, 7-tetrachloro-2 inverted exclamation marka,4 inverted exclamation marka,5 inverted exclamation marka,7 inverted exclamation marka-spiro[isobenzofuran-1(3H), 9 inverted exclamation marka-[9H]xanthen]-3-one 61738-01-0 Rose Bengal diacetate Spiro[isobenzofuran-1(3H), 9 inverted exclamation marka-[9H]xanthen]-3-one is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1057.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3 inverted exclamation marka,6 inverted exclamation marka-bis(Acetyloxy)-4,5,6, 7-tetrachloro-2 inverted exclamation marka,4 inverted exclamation marka,5 inverted exclamation marka,7 inverted exclamation marka-spiro[isobenzofuran-1(3H), 9 inverted exclamation marka-[9H]xanthen]-3-one 61738-01-0 Rose Bengal diacetate Spiro[isobenzofuran-1(3H), 9 inverted exclamation marka-[9H]xanthen]-3-one 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.
