Description

8S64APH24W 88-95-9 Phthaloyl chloride 1,2-Phthaloyl dichloride 1,2-Benzenedicarbonyl dichloride Phthaloyl chloride (8CI) Phthaloyl dichloride 1,2-Bis(chlorocarbonyl)benzene EINECS 201-869-0 NSC 44611 Phthalic acid dichloride Phthalic chloride Phthalic dichloride Phthalyl chloride Phthalyl dichloride CCRIS 8625 UNII-8S64APH24W EC 201-869-0 (CAS 88-95-9) is a high-purity analytical reference standard with the molecular formula C8H10Cl2O2 and a molecular weight of 209.07 g/mol.

8S64APH24W 88-95-9 Phthaloyl chloride 1,2-Phthaloyl dichloride 1,2-Benzenedicarbonyl dichloride Phthaloyl chloride (8CI) Phthaloyl dichloride 1,2-Bis(chlorocarbonyl)benzene EINECS 201-869-0 NSC 44611 Phthalic acid dichloride Phthalic chloride Phthalic dichloride Phthalyl chloride Phthalyl dichloride CCRIS 8625 UNII-8S64APH24W EC 201-869-0 (C8H10Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 8S64APH24W 88-95-9 Phthaloyl chloride 1,2-Phthaloyl dichloride 1,2-Benzenedicarbonyl dichloride Phthaloyl chloride (8CI) Phthaloyl dichloride 1,2-Bis(chlorocarbonyl)benzene EINECS 201-869-0 NSC 44611 Phthalic acid dichloride Phthalic chloride Phthalic dichloride Phthalyl chloride Phthalyl dichloride CCRIS 8625 UNII-8S64APH24W EC 201-869-0 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.
