The molecular framework of 95UD7B188K 618-83-7 5-Hydroxyisophthalic acid 1,3-Benzenedicarboxylic acid, 5-hydroxy- Isophthalic acid, 5-hydroxy- (6CI,7CI,8CI) 4-10-00-02098 (Beilstein Handbook Reference) BRN 2693561 EINECS 210-565-7 5-Hydroxy-1,3-benzenedicarboxylic acid Isophthalic acid, 5-hydroxy- NSC 302088 5-Oxyisophthalic acid 5-Hydoxyisophthalic acid EC 210-565-7 UNII-95UD7B188K (C8H12O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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 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), 95UD7B188K 618-83-7 5-Hydroxyisophthalic acid 1,3-Benzenedicarboxylic acid, 5-hydroxy- Isophthalic acid, 5-hydroxy- (6CI,7CI,8CI) 4-10-00-02098 (Beilstein Handbook Reference) BRN 2693561 EINECS 210-565-7 5-Hydroxy-1,3-benzenedicarboxylic acid Isophthalic acid, 5-hydroxy- NSC 302088 5-Oxyisophthalic acid 5-Hydoxyisophthalic acid EC 210-565-7 UNII-95UD7B188K meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
