Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

5866PEO79W 4422-95-1 1,3,5-Benzene-tricarbonyl trichloride 1,3,5-Benzenetricarbonyl trichloride 1,3,5-Benzenetricarbonyl chloride 1,3,5-Benzenetricarboxylic acid chloride 1,3,5-Benzenetricarboxylic chloride EINECS 224-594-8 NSC 82328 Trimesic acid trichloride Trimesoyl chloride UNII-5866PEO79W (CAS 4422-95-1), molecular formula C9H9Cl3O3 and molecular weight 271.52 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5866PEO79W 4422-95-1 1,3,5-Benzene-tricarbonyl trichloride 1,3,5-Benzenetricarbonyl trichloride 1,3,5-Benzenetricarbonyl chloride 1,3,5-Benzenetricarboxylic acid chloride 1,3,5-Benzenetricarboxylic chloride EINECS 224-594-8 NSC 82328 Trimesic acid trichloride Trimesoyl chloride UNII-5866PEO79W (C9H9Cl3O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 5866PEO79W 4422-95-1 1,3,5-Benzene-tricarbonyl trichloride 1,3,5-Benzenetricarbonyl trichloride 1,3,5-Benzenetricarbonyl chloride 1,3,5-Benzenetricarboxylic acid chloride 1,3,5-Benzenetricarboxylic chloride EINECS 224-594-8 NSC 82328 Trimesic acid trichloride Trimesoyl chloride UNII-5866PEO79W under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
