Structurally, 6A3LDJ6CL3 99-63-8 1,3-Benzenedicarbonyl chloride Isophthaloyl dichloride 1,3-Benzenedicarbonyl dichloride Isophthaloyl chloride 4-09-00-03295 (Beilstein Handbook Reference) m-Benzenedicarbonyl chloride 1,3-Benzenedicarboxylic acid, dichloride BRN 0638342 Dichlorid kyseliny isoftalove [Czech] EINECS 202-774-7 HSDB 5326 Isophthalic acid chloride Isophthalic acid dichloride Isophthalic chloride Isophthalyl chloride Isophthalyl dichloride Isothaloyl chloride NSC 41884 m-Phthalic dichloride m-Phthaloyl chloride meta-Phthalyl dichloride m-Phthalyl dichloride Dichlorid kyseliny isoftalove UNII-6A3LDJ6CL3 EC 202-774-7 (C8H10Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 209.07 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
