Chemical Structure
Description
The occurrence of 1,3-Isobenzofurandione, hexahydro-, polymer with 2-(chloromethyl)oxirane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Isobenzofurandione, hexahydro-, polymer with 2-(chloromethyl)oxirane (CAS 31095-87-1), molecular formula C8H10O3C3H5ClO and molecular weight 246.69 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1,3-Isobenzofurandione, hexahydro-, polymer with 2-(chloromethyl)oxirane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1,3-Isobenzofurandione, hexahydro-, polymer with 2-(chloromethyl)oxirane 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.
